Write an equation of a line that passes through the two given points. Your answer should be written in slope-intercept form.

P(3, 0), Q(4, 6)

Two points = (3, 0), (4, -6)

Slope = m = (0 - (-6))/(3 - 4) = -6

Equation of line will be

(y - 0) = -6(x - 3)

y = -6x + 18

y = mx + b

m = -6

y-intercept = 18
