Creating and Graphing Linear Equations IA #2

Caroline’s Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month Sean spent $26.95 on a mug and refills. How many refills did he buy?
What is the correct equation to solve?

• 8.95 + 1.5r = 26.95
• 8.95r + 1.5 = 26.95
• 26.95 + 1.5r = 8.95
• 8.95 + 1.5 = 26.95r

Jasmine’s cell phone company charges her $35 an month for phone service plus 0.50 for each text message. How many text messages does Jasmine send in a month if her bill was $52?
What is the correct equation to solve?

• 35t + 0.5 = 52
• 35 + 0.5 = 52t
• 35 + 0.5t = 52
• 52 + 0.5t = 35

In slope intercept form (y=mx+b) what is the "m"?

• The y-intercept
• The x-intercept
• The slope (rate of change)
• A point

Find the equation of the line in slope-intercept form. 

• y = - 1/4x - 3
• y = 1/3x + 3
• y = - 1/4x + 2
• y = 1/3x -3

Find the slope of the line that passes through the points (2, 4) and (6, 12)

• 1/2
• -1/2
• 2
• -2

Which equation is being represented by this line?

• y = -1x + 2
• y = 1/2x + 2
• y = 3x -4
• y = -3x +2

Write in slope-intercept form:
-3x + 4y = 12

• y = 3/4x + 3
• y = -3/4 x + 3
• y = -4x + 3
• y = 4x + 3

Write in slope intercept form
5x - 3y = -9

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

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

• A
• B
• C
• D
