Question

Graph the function.

Answer 1

The answer is totally D

Answer 2

Answer:

The correct option is D.

Step-by-step explanation:

If a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

From the given graph it is clear that the line is passing through the points (-1,2) and (0,-1), so the equation of line is

$y-2=\frac{-1-2}{0-(-1)}(x-(-1))$

$y-2=-3(x+1)$

$y-2=-3x-3$

$y=-3x-3+2$

$y=-3x-1$

The correct formula for the function is y=-3x-1, therefore the correct option is D.
