Linear Equations - point-slope form review

Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

• m = (y₂ - y₁)/(x₂ - x₁)

For the equation
y - 3 = 2(x + 4),
which of the following is true?

• The line has m = 2 passing through the point (4, -3)
• The line has m = 2 passing through the point (3, -4)
• The line has m = 2 passing through the point (-4, 3)
• The line has m = 2 passing through the point (-3, 4)

Write the equation in point-slope form of the line that passes through the given point and has the given slope.

(4, -7); m = ^-1/₄

• y - 7 = ^-1/₄(x - 4)

• y - 4 = ^-1/₄(x + 7)

• y+ 7 = 4(x - 4)

• y + 7 = ^-1/₄(x - 4)

Select ALL that could not represent the line containing the points

(-2, -3), (4, 3)

• y - 3 = 1(x - 4)

• y + 3 = 1(x + 2)

• y - 3 = 1(x + 2)

• y + 3 = 1(x + 4)

Which of the following could not be an equation for the line shown

• y = 2x + 7
• y - 3 = 2(x + 2)
• y + 3 = 2(x + 5)
• y + 3 =2(x + 2)
