Question

. For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.

Answer 1

To find the x and y-intercept you plug in zero for the corresponding value that you are looking for. For example, if you are looking for x, plug 0 in for y.

To solve x-intercept:                                    To solve y-intercept:
0=-2x-3    add 3 to other side                      y=-2(0)-3  substitute 0 for x
3= -2x       divide 3 by -2 to isolate x           y= 0-3
3/-2 = x     (3/-2 , 0) is your x intercept        y=-3          ( 0,3) is your y-intercept.
  
I hope this helps...
