Question 316663
To find the slope of each line, you will need to change each equation into slope intercept form: y = mx + b
m = slope, b = y-intercept

For the example you provided:  15 + 3y = 4x

First, you would get 3y by itself by subtracting the 15 from the left and right side of the equation.

{{{3y = 4x - 15}}}

Now, you want to get 'y' completely by itself by dividing 3 into itself and each term on the right side of the equation.

{{{3y/3 = (4/3)x - 15/3}}}

Simplify:

{{{y = (4/3)x - 5}}}

Now, you found the value of m, slope, which equals (4/3)
