What is the equation of the line that goes through these points?

• y = 3x + 3

• y = 3x + 2

• y = 2x + 3

• y = 3x + 7 

Write the equation in Standard Form:
y - 5 = 1/3(x + 8)

• -x + 3y = 23

• y = 1/3x + 23/3

• x - 3y = -13

• x - 3y = - 23

For the equation
y - 3 = 2(x + 4),
the line has a slope of 2 and contains what point?

• (-4, 3)

• (3, -4)

• (-3, -4)

• (-4, -3)
