Question

The graph of a linear function h contains the points given in the table below.

Answer 1

The basic form of linear function is

y=ax+b

For finding the slope, use the slope formula.

(4-2)/(-2+1)= 2/-1=-2

We first found a which is -2.

Then insert any point to find the value of b. In this case, I will insert (1,-2).

-2=-2+b

b=-2+2=0

The linear graph is y=-2x
