Simply plug in the points

Plug in -1 as X and solve for y
This gives the k value as well
3. y=-5x + 12
Use the point slope formula
Y2-Y1= m(x2-x1) + b
Answer:
1.) Ans -2 , 14
2.) Ans 2 1/5
3.) Ans y= mx+c
Step-by-step explanation:
first one you use Y = Mx +c
You see the Mx is a multiplication
and you input.
M * x = -5 x 2
M* x = -5 x -1
M* x = -5 x 3
M* x = -5 x -2
and note the answers will be less 4 as the equation states +4 is the y intercept and balances the equation.
So answers of the above in same order are;
-10
5
-15
10
we add 4
-6
9
-11
14
and see that 14 is the correct answer for y.
So the correct coordinates are -2, 14
Question 2) coordinates -1 k can equal = -5x+3
First we write as a division we know the gradient is -5
-we eliminate x
5x-1 / k+3
= 4x/k+3
M = -5
= 4x = -5(k+3)
= 4x = -5k +15
= 4x -15 =-5k
= -11 =-5k
= 11/-5 = k
k = 2 1/5
3) Ans The equation of a line is y=(input the number whatever times the x to make the number before you add)
y = m
3) Ans then you place x next to it
3) Ans then you place + 4 or whatever adds to the number.
So the equation of the line is what makes y its value through m the gradient being the number you times with x and the difference of that total to make y intercept.
Find y intercept and you have c of Mx+c

The diagram shows 3 vertices of a parallelogram.
Plot the 3 possible points for the 4th vertex.
Answers
Answer:
(-1, -1), (-3,5), (5, -3)
Step-by-step explanation:
(-1, -1) is the 4th vertex.
Which is the required vertex ?Let, 4th vertex is (x, y)
Given vertices of parallelogram are (-2. 2), (1, 1), (2, -2)
Here, (-2. 2) & (2, -2) are opposite vertices.
So, Midpoint of diagonals = [tex][(\frac{-2+2}{2}) ,(\frac{2-2}{2})][/tex] = (0, 0)
This is also midpoint of diagonal with vertices (1, 1) & (x, y)
So, (1+x)/2=0 ⇒ x = -1
& (1+y)/2=0 ⇒ y = -1
∴ 4th vertex is (-1, -1)

O y= √x+5
O y= √x+5
O y=√x-5
Answers
Answer: A is the correct answer .
Start with the last two choices .
You have x+ 5 and × - 5 in the square root .
A square root can never be negative .
That means that the lowest value of y can have in the last two choices is 0 .
Now range doesn't include -4.
Now look at choice B .
sqrt (x) is at least 0.
Then you add 5 .
The range doesn't include -4.
Now look at choice A .
sqrt (x) is at lest 0 .
Now ,you subract 5 .
The lowest value y can have is -5 . That includes -4.

Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2
The legs are r and 12
The hypotenuse is (8+r)
r^2 + 12^2 = (8+r)^2
r^2 + 144 = 64 + r^2 +16r
Subtract r^2 from each side
144 = 64 +16r
Subtract 64 from each side
144-64 = 16r
80 = 16r
Divide each side by 16
80/16 = 16r/16
5 =r

One supplementary angle is 15 degrees less than twice the other. Find the measure of the two supplementary angles.
Answers
Hey there!
To find our answer, we need to set up a system of equations. Remember, supplementary angles equal 180 degrees when combined. We will call one of our angles A and the other one B. Let's set it up below! :)
A=2B-15 (one angle is 15 degrees less than twice the other)
A+B=180
We need to find one of our variables. To do this, we only put one variable in the equation. But how, there are two variables in both equations! Well, as you can see, we see the A is equal to 2B-15, so we can take 2B-15 and put it into the second equation in place of A because it is equal to A, and then we will only have Bs and we can solve for it. This method is known as solving systems of equations with substitution.
Let's solve with substitution!
2B-15+B=180
3B-15=180 We combine our Bs.
3B=195 We add 15 to both sides.
B= 65 We divide both sides by three.
Now, we need to find what A is, but this will be really easy to do! If you remember, our angles are supplementary, so when you combine them, we will get 180, as you can see in our second equation in our first system of equations. So, we simply subtract 65 from 180.
180-65=115
Our two angles are 65° and 115°.
We can also check this with the original problem.
If you double 65, we have 130. Then, if we subtract 15, we have 115. Systems of equations are a pretty awesome way to figure this out!
I hope this helps! Have a great day!
