Can somebody show me how to change 3x+2y=26 into y=mx+b?

3x + 2y = 26    ==> y = mx + b

Basically, you would make y isolated.

So, subtract 3x from both sides.

2y = -3x + 26

Divide both sides by 2.

y = -3/2x + 13

Where m = slope, 13 = y-intercept

~Hope I helped!~

3x + 2y = 26
     - 2y     -2y
3x = 26 - 2y
-26   -26
3x - 26 = -2y

m = slope
b = x-intercept
y = y-intercept

The answer to that question your asking is 64
