Which statements are true about the line pairs?

• Line a and Line b have the same y-intercepts.

• Line b and Line c have the same slopes.

• Line a and Line b have the same slopes

• Line b and Line c have the same y-intercepts.

Multiple Choice

What is the correct equation of the line in the graph ?

Match

Match each slope and y-intercept to the correct equation of the line.

• Slope: 3; y-intercept: (0, -5)

• Slope: -5; y-intercept: (0, 3)

• Slope: -3; y-intercept: (0, 5)

y = 3x-5

y = -5x+3

y = -3x+5

• y = 3x-5

• y = -5x+3

• y = -3x+5

Match

The volume of liquid in a cylinder is 50mL. Every time a marble is added to the cylinder, the volume increases by 2mL.

Match the statement with its corresponding number or variable in the equation y = 2x + 50.

• The total volume of the cylinder after marbles are added

• The volume of each marble, or the rate of change

• The number of marbles added to the cylinder

• The initial volume before marbles are added to the cylinder or the y-intercept

Multiple Choice

What is the equation of the line in the graph?

Match

Match each description of the line to the correct equation of the line

• Slope of 3; crosses through the point (5, -6)

• Y- intercept at (0, -15); crosses through the points (4, -9) and (8,-3)

• Slope of 2; crosses through the point (1,5)

y=3x-21

y=3/2x-15

y=2x+3

• y=3x-21

• y=3/2x-15

• y=2x+3
