In the equation y=mx+b, what does the m and the b represent?

• slope and y-intercept

• move and bump

• up and down

• left and right

What is the slope of the line with the equation
 $y\ =\ \frac{5}{6}x\ -\ 2$  

•  $-\frac{5}{6}$  

•  $\frac{5}{6}$  

•  $2$  

•  $-2$  

What is the equation of a line when m = 7 and b = 2?

• y = 7x + 2

• y = -7x - 2

• y = -7x + 2

• y = -2x - 7

If you have a slope of 3/5 that means you could...

• Go up 3 and right 5 units.

• Go right 3 and up 5 units.

• Go left 3 and down 5.

Solve for y:

2x + 5y = 10

• y = -2/5x + 2

• y = 2/5x + 2

• y = -5/2x + 2

• y = -5/2x - 2

8x + 4(3x - 5) = 20

• 4

• 3

• 2

• 1

If y varies directly with x, and y = -10 when x = 4, what is y when x = 24?

• 60

• -1.67

• 1.67

• -60

Erica's paycheck earnings varies directly as the number of hours she works. If she works 20 hours and earns $125.75, what should she earn if she worked 40 hours?

• $251.50

• $62.88

• $125.75

• $0

Write the equation of the line in Point-Slope form that goes through the point (7, 8) and has a slope of 5

• y - 8 = 5(x - 7)

• y= -5x + 35

• y + 8 = 5(x + 7)

• y= -5x - 35

Write the equation in slope-intercept form for the line that contains the points

(0, -5) and (3, 1)

• y = -2x - 5

• y = 2x + 1

• y = 2x - 1

• y = 2x - 5
