Question

Find the y-intercept of the graph of the linear equation. Give your answer in terms of b.

3y=mx+b

Answer 1

3Y=mx+b
Y=1/3(mx)+b/3
Y-intercept =1/3 b

Answer 2

To find the y-intercept, solve the equation for the slope-intercept form.

`3y = mx + b\\[0.5em] ~~y = (1)/(3)mx + (1)/(3)b`

So the y-intercept is the back piece, the 1/3 b.
