A line has a slope of -3/17 and its y-intercept is (0,18) . What is its x-intercept?

y=-3/17x+18

0=-3/17x+18

-18=-3/17x

-18*-17/3=x

x=6*17

x=102

point slope form of the line is    (y-18) = -3/17 (x)      sub in 0 for y

                                                      -18 = - 3/17 x

                                                          x = 17/3 * 18 = 102
