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

to get `x-intercept`, plug in `y=0` in y = -2x-3 to get `y-intercept`, plug in `x=0` in y = -2x-3

hartnn (hartnn):

x-intercept: 0 = -2x-3 can you get the value of x ?

OpenStudy (anonymous):

im still here sorry

hartnn (hartnn):

ok :) can you solve for x in 0 = -2x-3 ?

hartnn (hartnn):

you mean x = -3/2 correct! so x intercept is (-3/2, 0) :)

OpenStudy (anonymous):

Thank you for your patience.

hartnn (hartnn):

and y intercept : put x=0 you get y = -3 y intercept = (0,-3) :)

hartnn (hartnn):

welcome ^_^
