Convert the equation to slope-intercept form, y=mx%2Bb where m is the slope and b is the y-intercept.
15%2B3y=4x
3y=4x-15
y=%284%2F3%29x-5

Slope: m=4%2F3

Y-intercept: b=-5:(0,-5)

15%2B3y=4x you will want to set up equation in slope-intercept form y=mx+b
3y=4x-15 i subtracted 15
y=%284%2F3%29x-5 i divided by 3
this is in the correct form so now u can see where m=slope and b=yintercept
so highlight%28m=%284%2F3%29%29 and b=-5

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%2F3+=+%284%2F3%29x+-+15%2F3
Simplify:
y+=+%284%2F3%29x+-+5
Now, you found the value of m, slope, which equals (4/3)

Solve the equation for in terms of everything else. That is to say do whatever is necessary to put the equation in the following form:



Once you have done that, the slope is whatever the coefficient on (the in the equation above) turns out to be.

Your example:



Add to both sides:



Multiply both sides by



And there is the slope staring you right in the face right next to the .
