Given a line passes through the y intercept of -1, and goes through the points (1,2) and (3,8), what is the equation of the line?

y = 3x - 1

Solving Equations

100

2x + 6 =0

x = -3

200

2x - 18 = -3x + 27

x = 9

300

7x + 42 = -3x - 28

x = -7

400

(x - 5)(x + 3) = 0

x = 5 or x = -3

500

x^2 - 9x + 18 = 0

x = 6 or x =3
