How do you find the coordinates of the x intercept for this equation?
-x + 5y = -15
-x + 5y = -15
To find the x-intercept, put 0 in for y, because at the x-intercept (where the line
crosses the x-axis) the y-coordinate is 0
-x + 5y = -15
-x + 5(0) = -15 {substituted 0 in for y}
-x = -15 {multiplied 5 by 0}
x = 15 {the x-intercept}
(15,0) {where the line crosses the x-axis}
