Linear Equations Forms

Find the x and y intercepts
5x - 3y = 15

• x intercept is 3 
  y intercept is 5

• x intercept is -3
  y intercept is 5

• x intercept is 5
  y intercept is -3

• x intercept is 3
  y intercept is -5

Find the x and y intercepts
4x - 5y = 40

• x intercept is 10 
  y intercept is 8

• x intercept is 10
  y intercept is 20

• x intercept is 8
  y intercept is 10

• x intercept is 10
  y intercept is -8

Change the following equation to slope-intercept form:
5x - 5y = 25

• y = x - 5

• y = 5x - 1

• y = -x + 5

• y = 5x + 1

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

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

Match the different forms of a linear equation

• Ax+By=C

• standard form

• y-y₁=m(x-x₁)

• point-slope form

• y=mx+b

• slope-intercept form

Answer explanation

Match the following:

• Slope-Intercept Form

• Standard Form

• Point-Slope Form

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)

Change the following equation to slope intercept form:
y + 2 = -3(x - 5)

• y = -3x + 17

• y = -3x + 13

• y = -3x - 13

• y = -3x - 17
