Solve for y in terms of x and arrange into the form, y=mx+b.
(Just tell her that).

Also for more guidance,
Ax%2BBy=C
y=-Ax%2BC
y=-%28A%2FB%29x%2BC%2FB---------How the parts correspond should make sense to her.

Standard Form 3x%2B4y=8

Solve for y in terms of x.
3x%2B4y-3x=8-3x
4y=8-3x
4y=-3x%2B8
%281%2F4%294y=%281%2F4%29%28-3x%2B8%29
highlight%28y=-3x%2F4%2B2%29-----------------and arranged into slope-intercept form.
This can also be shown as highlight%28y=-%283%2F4%29x%2B2%29.
