Question

Change 4x - 3y = -15 to slope-intercept form and state the slope and y-intercept.

Answer 1

Solve for y

Answer 2

Ok you have the line in the form of

Ax+By=C
and they want you to convert it into the slope intercept form
y=mx+b
because then m is the slope and b is the y intercept.

Ax+By=C
By=C-Ax
y = C/B -(A/B)x

or an example with numbers.

if
10x +20y = 40
20y = 40-10x
y = 40/20 -(10/20)x
y= -(1/2)x +2 ====== slope intercept form
Now repeat with your equation
