Answer Choice $D$ : $y = 3x - 2$
We need to find the slope-intercept form of the table shown to the right. $y = mx + b$ The formula for slope is $\frac{y_2 - y_1}{x_2-x_1}$. Let's say we take the coordinates $(-3,-11)$ and $(0,-2)$ $\frac{-2- (-11)}{0 - (-3)}$ = $\frac{9}{3}$ = $3$ Now, replace $m$ with $3$ $y = 3x + b$ The value of $y$ when $x$ is 0 is $-2$. Replace $b$ with $-2$ $y = 3x - 2$ The answer is $D$
