The slope is m=-1
Because the formula is y=mx+b (b is the intercept) (or replace 0 with x so that will be y=7)
And the Y intercept is 7 :)
I hope this helped!
Answer:
(0, - 4 )
Step-by-step explanation:
under a counterclockwise rotation about the origin of 180°
a point (x, y ) → (- x, - y ), hence
C(2, 4) → (- 2, - 4)
A translation of 2 units to the right means add 2 to the original x- coordinate while the y-coordinate remains unchanged.
(- 2, - 4 ) → (- 2 + 2, - 4 ) → (0, - 4 )

Cross multiply..
1x = 12.8
Divide 1 from both sides
=
x = 12.8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let's check our answer now..
=
Cross multiply
12.8 = 12.8
Your answer is 12.8 :)
Answer:
y = (- 7/8)*x - 1.5
Step-by-step explanation:
One point is (-4,2) and the other one is (4,-5)
The first step is to find the slope.
m = (y2 - y1) / (x2 - x1)
- y2 = 2
- y1 = -5
- x2 = -4
- x1 = 4
Solution
<em><u>Find the slope</u></em>
m = (2 - - 5) / (-4 - 4)
m = (2 + 5) / (- 8)
m = 7 / - 8
So far what you have is y = (-7/8)x + b
Find the y intercept.
Use (4,-5)
y = (-7/8)x + b
x = 4
y = - 5
-5 = (-7/8) * 4 + b
-5 = -7/2 + b
-5 = - 3.5 + b Add 3.5 to both sides.
-5 + 3.5= - 3.5+ 3.5 + b
- 1.5 = b
