Point Slope and Writing Equations Progress Quiz

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

• y - y₁ = m(x - x₁)
• Ax + By = C
• y = mx + b

What does "m" represent in y - y₁ = m(x - x₁)?

• y-intercept

• slope

• macaroni

• nothing

Write the slope-intercept form of the equation with the given point and slope.

m = 5 through ( - 1, - 3 )

• y = 5x + 2

• y = - 5x - 5

• y = - 5x + 2

• y = 2x - 5

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)
