Point-Slope Review

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

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

• y-intercept

• slope

• macaroni

• nothing

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)
