Write the equation for each line in form Ax+By=C using slope=3 and y intercept (0,-2)?
start with y-intercept form because that's what you're given:





y = 3x-2





subtract 3x from both sides:





-3x + y = -2





multiply through by -1 because A should not be negative:





3x - y = 2





that's it!
