Linear Equations Review

The y intercept is AWESOME! It helps us to know...

• Where our line will end.

• If our line is positive or negative.

• Where to start graphing our line.

Which graph best represents the equation y = -3x + 4?

• 
• 
• 
• 

• -2
• 3
• 5
• Cannot be Determined

Which Graph is Linear?

• 1st
• 2nd

• 3rd
• None

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)

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 slope-intercept form for the line that contains the points
(3, -5) and (5, - 1)

• y = 2x + 11
• y = 2x + 1
• y = 2x - 1
• y = 2x - 11

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

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• -7x + 2y = 9
• 3x + 2 = y

Convert the standard form equation into slope-intercept form.
x - 5y = 10

• y = ⅕x - 2
• y = -x - 2
• x = -10
• y = 27, 239, 430
