@bibby Demonstrating the Intercept Form is an acceptable response. It is also acceptable to assist a student in obtaining tools, then watching the student progress over the course of a few questions.

@harleeekoon You could try the Intercept form, as previously demonstrated.

the formula for the y intercept is mx+b so what you have to do is first get y on one side to do that you could subtract 5x from one side as so: 5x+8y=-24
                                                                           -5x        -5x
then you would have 8y=-5x-24 then to get rid of the 8 you would divide each side by 8 as so: 8y(underline then put 8 on bottom) then underline the -5x-24 then put 8 on the bottom. the 8s cancel out so your left with y= -5x-24
                                                                         8
then simply divide the -24 by 8 which is 3 so the slope intercept is y=-5x-3
