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=-(1)/(2)x-3\rightarrow 0=-(1)/(2)x-3`

`3=-(1)/(2)x` which becomes
`3*-(2)/(1)=x=3*-2=-6`
So your x-intercept is (-6,0)

To get y-intercepts: set the x value to 0.

`y=-(1)/(2)-3\rightarrow y=-(1)/(2)(0)-3`

`y=0-3=-3`
So your y-intercept is (0,-3)
