Question 166110
x + 3y = 15 

solve for 'm' and 'b'. 


You need to write the equation in the y-intercept form y = mx + b, 
where m = slope and b = y-intercept.

x + 3y = 15
 
We want to isolate y.

Subtract x from both sides.

Doing so, we get this:

3y = -x + 15

We now divide both sides by 3 to isolate y.

y = (-1/3)x + 15

Final answer: m = (-1/3) and b = 15
