Point-Slope Form

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

• Ax + By = C

• y - y₁ = m(x - x₁)

• y = mx + b

Answer explanation

To write the equation, plug in the point and slope!

m=1/2 (-2 , 1)

y- _____ = _____ (x- _____)

For the equation y + 1 = -3(x - 5), the line contains the point (5, -1) and has a slope of?

• -1

• 1

• -3

• 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

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

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)

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

• m = 1

• m = 3

• m = -4

• m = 2

For the equation  y - 4 = -1/3(x - 7),  what is the point that the line passes through?

• (4, 7)

• (-7, -4)

• (7, 4)

• (-4, -7)

Write the equation in point-slope form for the line that contains the points (-2, -3), (4, 3)
