when talking about y-intercept, you are finding where x = 0, and when finding the x-intercept, you are finding where y = 0.
Here, the y-intercept is -3 (look where x is 0)
Slope:
To find the slope, take any 2 points and use the equation:
Y2 - Y1
————— = m; m is the slope.
X2 - X1
As an example, I will take (1, -1) and (2, 1).
Y2 = 1
Y1 = -1
X2 = 2
X1 = 1
1 - (-1) 1+ 1
————— = ————— = 2/1 = 2
2 - 1 1
2 is the slope.
Or, observe how y always increases by 2 for every x (rise/run)
Equation:
Now, since we found the slope (2) and the y intercept, simply plug in the numbers into the linear equation form (y = mx + b). You should know that m means the slope and b means the y intercept. Meaning the equation is...
y = 2x - 3
Hope it helped :)

Find the 23rd term of this sequence -25,-15,-5,5....
Answers
Answer:
195
Step-by-step explanation:
To find the 23rd term of this sequence, we can use the arithmetic sequence formula [tex]a_{n} =a_{1} +(n-1)d[/tex] where,
[tex]a_{n}[/tex] = [tex]n^{th}[/tex] term
[tex]a_{1}[/tex] = first term
[tex]n[/tex] = term position
[tex]d[/tex] = common difference
[tex]a_{23}=-25+(23-1)10[/tex]
[tex]a_{23} =195[/tex]
Explain how to graph the point (6,4) on a coordinate plane.
Answers
Answer:
here is how
Step-by-step explanation:
the x (6) is the horixontal ways on the co-ordinate plane. you go right until you reach the six. the y (4) is vertical. take the point that is on 6,0. and move it up until you see it on 4. now you have the coordinates 6,4.

is the relation a function?
please help.
Answers
Answer:
Yes
Step-by-step explanation:
A function has one input (x-value) per output (y-value).
In other words, a relation that does not repeat any x values is a function.
{(3,4) , (5,0) , (2,4) , (-5,-5)}
The domain of the relation is:
{-5,2,3,5}
Since none of the numbers repeat in the domain, the relation is a function.

Answers
Answer:
x = - 5, x = - 11
Step-by-step explanation:
Given
y = [tex]\frac{x+4}{(x+5)(x+11)}[/tex]
The denominator cannot be zero as this would make y undefined.
Equating the denominator to zero and solving gives the values that x cannot be, that is
(x + 5)(x + 11) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x + 11 = 0 ⇒ x = - 11
Thus
x = - 11 and x = - 5 are excluded values.

What is the equation of the line that has a slope of –4 and passes through the point (2, 3)?
Answers
Answer:
y=-4x+11
Step-by-step explanation:
We can use the point-slope form of a line to solve this, which is
y - y₁ = m (x - x₁), where (x₁ , y₁) is a point and m is the slope.
We have:
y - 3 = -4(x - 2)
y - 3 = -4x + 8
y = -4x + 11

What is the length of Line segment A J if Line segment A B is parallel to lines segment J K?
8 in.
8.75 in.
10.25 in.
14 in.
Answers
Answer:
8.75 in.
Step-by-step explanation:
See attachment for the figure.
As you can see, ∆ HBA & ∆HKJ are similar,
HB/HA = HK/HJ
3/5.25 = 8/HJ
3HJ/5.25 = 8
3HJ = 42
HJ = 14 in.
AJ = 14 - 5.25
AJ = 8.75 in.
Therefore, the length of Line segment AJ is 8.75 in.

(B) 8.75

Answers
Answer:(15, 100)
Step-by-step explanation:
first find the coordinates of the point above (3, 20)
you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40
so the coordinate would be (6, 40)
now subtract (6, 40) by (3, 20)
6-3= 3
40- 20= 20
you get the first coordnites which is what you add (12,80) to
12 +3= 15
80+ 20= 100
you get the coordinates (15, 100)
