What is the y-intercept of a line that has a slope of m=5 and goes through the point (2,18)?

Answer 1

y=mx+ b

y=5x + b

18=5(2) + b

b = 18-10 = 8

y=5x + 8 has slope = 5 and goes through the point (2,18)

18=5(2) + 8 = 10+8 = 18

slope is the coefficient of the x term when the equation is solved for y
