Question

whatis the y-intercept and x-intercept of this line x-4y=12?

Answer 1

When you put a linear equation (line) into the form y=mx+b
m is the slope, and b is the y intercept. To find the x intercept you need to find what x is when y=0. So set y to zero to find the x intercept, and the same with y-set x to zero to find the y intercept.
