Midterm Review - Forms of Linear Equations

Give the x-intercept
3x + 8y = 24

• (8, 0)
• (0, 8)
• (3, 0)
• (0, 3)

Find the slope of the line.

• Undefined
• 0
• 1
• -1

Write the equation for the line passing through (5, 7) and (3, 1).

• y = 3x - 8
• y = ⅓x 
• y = -3x +10
• y = -⅓x + 2

A newspaper charges $10 for the first 2 lines of text and $3 for each additional line of text. Write an equation in point-slope form.

• y - 10 = 3(x - 2)
• y - 2 = 3(x - 10)
• 2x + 10y = 3
• y - 10 = 2 (x - 3)

John gets a new job and receives a $500 signing bonus. After that, he makes $200 a day. Write an equation in slope-intercept form.

• y = 200x + 500
• y = 500x + 200
• y = 500x - 200
• y = 200x - 500

• y=2x+7
• y=-3x-5
• y=2x-1
• y=2x+6

Which is the graph of y= -x + 2?

• A
• B
• C
• D

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)

What is the x and y intercept for the following equation ?
4x - 10y = 20

• x - int = 4    
  y-int = -10
• x-int = 5
  y-int = 2
• x - int = 5
  y int = -2
• x -int = 4
  y -int = -10

rewrite this

3x + 5y = 20

into the slope intercept form

( y = mx + b )

• y = 5x + 4

• y = - 3/5x + 4

• y = 3/5x + 4

• y = -5/3x + 4
