Identify the y-intercept of the line

 $y=-\frac{2}{3}x-8$  

• A.  $-\frac{2}{3}$  

• B. -8

• C. 0

• D. -2

Write the an equation for the graph shown.

• y = -2x + 2

• y = 2x + 2

• $y=\frac{1}{2}x+2$

• $y=-\frac{1}{2}x+2$

For the equation

y - 3 = 2(x + 4),

the line has a slope of 2 and contains what point?

• (-4, 3)

• (3, -4)

• (-3, -4)

• (-4, -3)

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

• $y+7=-\frac{1}{4}(x-4)$

• $y-4=-\frac{1}{4}(x+7)$
  

• $y+7=4(x-4)$
  

• $y-7=-\frac{1}{4}(x-4)$
  

Identify the x-intercept of the line described in the equation

 $6x-4y=36$  

• (-9,0)
  

• (6,0)

• (36,0)

• (2,0)

Identify the y-intercept of the line described in the equation

$6x-4y=36$

• (0,-9)
  

• (0,6)

• (0,36)

• (0,2)

At a pet store, it costs $5 to wash a cat and $7.50 to wash a dog.  Last week, the store made $60 from washing cats and dogs. Write a linear equation that could be used to find how many cats and dogs were washed.

• -5x + 7.5y = 60
• 5x + 7.5x = 60
• 5x - 7.5y = 60
• 5x + 7.5y = 60
