What is the x-intercept for the given graph?

• 1
• -2
• 2
• 1/2

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

True or false:
The x-intercept of a function ALWAYS occurs where y is equal to zero.

• True
• False

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

What is the formula for standard form?

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

Which equation is written in STANDARD form?

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

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)

Write an equation  
m = 5 through (-1, -3)

• y = 5x + 2
• y = -5x - 5
• y = -5x + 2
• y = 2x - 5

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3

• y - 5 = -3(x - 10)
• y= -3x + 35
• y + 5= -3(x + 10)
• y= -3x - 35

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

• -1
• 1
• -3
• 5
