Did I do this correctly:

Equation of a line:
y=1/3x+5

Finding x-intercept, you set y to 0

y=1/3x+5
0=1/3x+5
-5 x 3=x
-15=x

Finding y-intercept you set x to 0

y=1/3x+5
y=1/3 x 0 +5
y=5

* b=5 and b=y-intercept. But what if b is not given then how do i find y-intercept??

You did it correctly. If b was not given, you would have to have another point on the line to determine the intercept.

Thank-you so much.
