For this problem the key is knowing what slope-intercept form is.
.
y=mx%2Bb
.
To get the equation 3x-4y=20 into slope-intercept form we just got to move some of the numbers around.
.
Our initial equation: 3x-4y=20
.
The whole idea is to try and get y by itself like it is in the slope-intercept form.
.
To do so we will start by subtracting off the 3x from both sides:
.
-4y=-3x%2B20
.
Note: we want to put the 3x in front of the 20 because that's where x is located in the slope-intercept form.
.
Next we will divide by -4.
.
y=+-3x%2F-4%2B20%2F-4
y=%283%2F4%29x-5
.
Note: Its easier to graph and it looks like the slope-intercept form when each number is individually divided by -4 rather then the whole right side of the equation. You just have to remember to divide ever number by -4.
.
3x-4y=20 in slope-intercept form is:
y=%283%2F4%29x-5
