Converting to y = mx + c Form
Sometimes equations aren't given in the standard form. Here's how to rearrange them:
Example 1: 3x + 2y = 12
Step 1: Isolate the y term
2y = -3x + 12
Step 2: Divide everything by the coefficient of y
y = -3x/2 + 12/2
Step 3: Simplify
y = -1.5x + 6
So m = -1.5 and c = 6
Example 2: x - y + 4 = 0
Step 1: Rearrange to get y on its own
y = x + 4
So m = 1 and c = 4
