x y
0 –4
4 4
What are the slope and y-intercept of this function?


A.

1
2
2
1
​ .
The y-intercept is (0, –4).

B.
The slope is

​ .
The y-intercept is (–4, 0).

C.
The slope is –2.
The y-intercept is (0, –4).

D.
The slope is 2.
The y-intercept is (0, –4)

Answer 1

Find the slope first using m=y2-y1/x2-x1
-4-4/0-4 =2

The y intercept is when x=0.
One of the given points is (0,-4)
The y intercept is y=-4
