Answer:
x = y - b
------------ or, x = y - b/m
m
Step-by-step explanation:
Given: y = mx+b
First, we need to isolate the variable we're solving the equation for.
To do that, we'll subtract b from both sides.
y = mx + b
-b - b
y - b = mx
Then, to get x by itself we must divide the equation by m.
y - b = mx
---------------
m
Now, we have:
x = y - b
------------ or, x = y - b/m
m
