Step-by-step explanation:
Here is Slope-Intercept Form for a line: y=mx+b
m is the slope
b is the y intercept
The y intercept is basically the point on the y axis where the line touches.
I will do #3 for you.
Let's first look for the y intercept. We can see that the line touches the y axis at -4, so that's it.
Let's put it into our equation, plugging in -4 for b. This is what we have so far: y=mx-4
To complete this equation, we still need to find the slope, m.
To find it, look at the point where the y intercept is, and count how many units you need to go up or down the y axis, and then right or left the x axis to get to another point on the line. The slope is equal to the change in y ÷ the change in x.
So we see that there's another point on (-3, -2), so let's try to get there from the y intercept.
We need to move two units up and 3 to the left.
In terms of y, we went up +2, and in terms of x, we went down -3
So our slope is 2/-3 or -2/3.
Now that we have our slope (m) and y intercept (b), we can plug it into out Slope-Intercept Equation, plugging in -2/3 for m:
y=-2/3x-4.
We don't need to find x or y. This is our answer for 3. Using the same method, you should be able to find the equations for the rest of the graphs. Good luck.

What is the slope of the line that passes through
the points (-1,3) and (5, 7)?
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
For this situation we will use this equation:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
This lets us find the slope from a set of points (m being the slope of course), with each one representing a coordinate from our set. (e.g. 7 could be [tex]y_{2}[/tex])
First let's define which coordinates will represent each:
(-1,3): [tex]x_{1} ,y_{1}[/tex]
(5,7): [tex]x_{2} ,y_{2}[/tex]
Now that we have this, we can fill in our coordinates: [tex]m = \frac{7-3}{5-(-1)}[/tex]
Next we simplify: [tex]m = \frac{4}{5+1}[/tex] (double negative = positive)
And simplify some more: [tex]m = \frac{4}{6}[/tex]
Finally, we find the GCF (greatest common factor) of 4 and 6, which is 2, and divide by that to further simplify the fraction: [tex]m = \frac{2}{3}[/tex]
Therefore, the slope of the line that passes through the points (-1,3) and (5,7) is [tex]\frac{2}{3}[/tex].
a line that has a slope of -2/5 and passes through the origin
Answer:
Hi there!
Your answer is
y= -2/5x
Step-by-step explanation:
The coefficient of x is the slope. IF the y intercept was something other than the origin, that number would be added. Since it has a y int of (0,0), it is simply the equation above!

During the winter, you charge people $15 for going to their house to shovel, then $11 for every hour you shovel. If you shovel 3 driveways in one day and make $89 that day, how many hours did you spend shoveling?
Answer:
4
Step-by-step explanation:
15x3=45
89-45=44
11x4=44
Answer:
Spent 4 hours shoveling
Step-by-step explanation:
15 x 3 = 45
89 - 45 = 44

A sequence is shown below.
32, 26, 20, 14...
Which explicit formula can be used to determine the nth term in the sequence?
a^n =6n+38
a^n= -6n+38
a^n= -6n+32
a^n= 6n+32
Answer:
a^n = -6n + 32
Step-by-step explanation:
32 - 6 = 26
26 - 6 = 32 - 6.2 = 20
20 - 6 = 32 - 6.3 = 14
-> a^n = -6n + 32

What conclusion can be made?
Answer: B) The value of k must be between 1 and 2
The function f(x) has a restricted domain [1, 2] which means [tex]1 \le x \le 2[/tex]
So we can only pick inputs in that interval. If x = k, then [tex]1 \le k \le 2[/tex]
If f(x) = x2 + 4x + 9. find f(-2)
Answer: f (-2) 5
Your welcome
A function is a relation between two variables where one variable is the set of inputs that gives the other variables as output.
The value of the function at x = -2 is 5.
The domain of the function = 5.
The range of the function = -2.
What is a function?A function is a relation between a set of inputs called domains and it has one output called the range.
Example:
f(x) = x + 2
At x = 2,
f(2) = 2 + 2 = 4
Domain = 2
Range = 4
We have,
f(x) = x² + 4x + 9
We need to find the value of the function at x = -2.
Substitute x = -2 in f(x).
f (-2) = (-2)² + 4x(-2) + 9
f (-2) = 4 - 8 + 9
f (-2) = 5
Thus the value of the function at x = -2 is 5.

Find the values of a and b
Answer:
a = 14°
b = 36°
Step-by-step explanation:
4b - 12 + 48 = 180 (supplementary)
Rearrange
4b = 180 - 48 + 12
4b = 144
b = 36°
4a - 8 + 4b - 12 = 180 (supplementary)
sub b = 36 into equation
4a - 8 + 144 - 12 = 180
Rearrange
4a = 180 - 144 + 12 + 8
4a = 56
a = 14°

Would a step-up transformer or a step-down transformer be used to convert 260 volt AC current from a household input into a 13 volt AC output in a portable electric fan? Determine the ratio of the number of input wire coils to output wire coils on the transformer.
Answer:
20:1
Step-by-step explanation:
It is given that,
Input voltage = 260 volt
Output voltage = 13 volt
We need to find the ratio of the number of input wire coils to output wire coils on the transformer.
For a step-down transformer,
[tex]\dfrac{V_i}{V_o}=\dfrac{N_P}{N_S}\\\\\dfrac{N_P}{N_S}=\dfrac{260}{13}\\\\=\dfrac{20}{1}[/tex]
Hence, the required ratio is 20:1.
