What is the rate of change of y with respect to x?

• 10

• 17

• -10

• -17

Answer explanation

Remember:

Rate of change means slope

What is the equation in slope-intercept form of the line that passes through points

(-26, -11) and (39, 34)?

What are the slope and y-intercept of the graph of g?

A customer paid a total of $6.00 for 68 copies. Some of the copies were black/white and the rest were color.

- Each black/white copy cost $0.08

- Each color copy cost $0.15

Which system of equations can be used to find the number of black/white copies (b) and color copies (c)?

• b + c = 6.00

  .08b + .15c = 68

• b + c = 68

  .15b + .08c = 6.00

• b + c = 6.00

  .08b + .15c = 68

• b + c = 68

  .08b + .15c = 6.00

The table of values show a linear relationship between x and y.

What is the slope of the line represented by the table?

What is the equation in standard form of the line that passes through the point

(6,-1) and is parallel to the line represented by 8x + 3y = 15?

• 8x + 3y = -45

• 8x - 3y = -51

• 8x + 3y = 45

• 8x - 3y = 51

A part of linear function g is graphed on the grid.

Which inequalities best describes the domain and range of the part shown?

The table of ordered pairs represent some points on the graphs of lines f and g.

Which system of equations represents lines f and g?

• y = 1.75x + 3.5

  y = -4x - 8

• y = 1.75x + 3.5

  y = -4x - 2

• y = 3.5x + 1.75

  y = -4x - 8

• y = 3.5x + 1.75

  y = -4x - 2
