Equations Based on Graphs

Solve the system of inequalities by graphing.

• 

Which point is a solution?

• (0, 6)

• (-3, 4)

• (1, 0)

• (-4, 3)

Which equation matches the graph? (Click me to see the image)

• y = 2x

• y = 1/4 x + 2

• y = 1x + 4

• y = -2x

Which is the graph of y= -x + 2? 

• A

• B

• C

• D

In this equation, what is the y-intercept?

^{y = 3x - 4}

• 3

• -4

• 4

• 3x

Which equation matches the table?

• y = x + 5

• y = 6x

• y = x + 6

• times 6

• y=2/4x+.5
• y=-2/4x+.5
• y=4/2x+.5
• y=-4/2x+.5

Use the graph to determine an equation to represent the relationship. Use t for minutes (time), and m for miles.

• 5t = m

• 5m = t

Use a point on the graph to reduce to the unit rate.

• $7.50 per pound of chicken salad

• $1 per pound of chicken salad

• 7.5 pounds of chicken salad per dollar

• $15 for 2 pounds of chicken salad

Which equation would be use to create the graph above?

• y = 50x

• y = 2x

• y = 0.02x
