Answer

$y = 3x - 18$

Work Step by Step

The Slope is 3, the X-Intercept is 6. So we know that m=3, and the line passes through (6,0) [X-Intercept is 6]: Now with a point and the slope we can use the formula: $y - Y_1 = m(x - X_1)$ Let's replace the values with the point and the slope: $y - 0 =3 (x - 6)$ $y = 3x - 18$ $y = x + 5$
