m= 5

(2, 4)

• y - 2= 5(x - 4)

• y - 4= 5(x - 2)

• y- 5 = 4(x - 2)

• y - 2 = 4(x - 5)

m= 3

(1, 7)

• y - 7 = 3( x - 1)

• y - 1 = 3( x - 7)

• y - 3 = 3( x - 1)

• y - 1 = 7( x - 3)

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

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

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)

If I want to write the equation in slope-intercept form Y=mx+b then I also need to know what?

• x-intercept

• y-intercept

• incline

Convert from point-slope form to slope-intercept form:

y - 2 = -5(x + 1)

• y = 5x + 3

• y = -5x - 3

• y = -5x + 7

Convert from point-slope form to slope-intercept form:

y + 3 = 4(x + 1)

• y = 4x + 2

• y = 4x - 2

• y = 4x+ 1

Given y + 6 = 10( x - 9) , what is the point used to write this equation?

• (10, 9)

• (6, -9)

• (-6, 9)

• (9, -6)
