Question

Write an equation in slope intercept form given the graph below.
x
-2
-1
0
1
y
2
-3
-8
-13
Answer

y = -5x – 8

y = -1/5x + 8

y = -3x + 8

y = 1/3x – 8

Answer 1

D or C?

Answer 2

its either a or b since the y intercept is -8 (given the point (0,8))
now just find the slope between two points, easiest by plugging in the y intercept and a set of points into y=mx+b:\[2=m(-2)-8\]\[2=-2m-8\]\[10=-2m\]\[m=-5\]so in conclusion the equation is:\[y=-5x-8\]option A :)
