Write the equation of the line in standard form through the points (-6, -19) and (2, 5).

• -3x - y = -1

• -3x + y = 1

• 3x - y = 1

• y = 3x - 1

Write an equation of the line in point slope form containing (-1,1) and (4,-9).

• y +1 = - 2(x - 1)

• y = -2x - 1

• y - 1 = - 2(x + 1)

• 2x + y = -1

Which of the following is the slope-intercept form?

• m = (y₂ - y₁)/(x₂ - x₁)

• y = mx + b

CCSS.8.F.A.3

Which of the following is the equation of the line that has a slope of 3 and passes through the point (0, 9)?

• y = -3x + 12

• y = 3(x + 9)

• y = 3x + 9

• y = 3x - 3

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = - 2

• 3x - 2y = 2
