Question

Plot the x- and y-intercepts to graph the equation. y=−1/2x−3

Answer 1

To get x-intercepts: set the y value to 0.
$y=-\frac{1}{2}x-3\rightarrow 0=-\frac{1}{2}x-3$
$3=-\frac{1}{2}x$ which becomes $3\times-\frac{2}{1}=x=3\times-2=-6$
So your x-intercept is (-6,0)

To get y-intercepts: set the x value to 0.
$y=-\frac{1}{2}-3\rightarrow y=-\frac{1}{2}(0)-3$
$y=0-3=-3$
So your y-intercept is (0,-3)
