Answer:

Point = (6, 8)

Rate of change = -1

Rate of change = 17.5

$0.62

Explanation:

Any point on the coordinate plane is (x, y).

  • x represents the location of the point with respect to the x-axis.
  • y represents the location of the point with respect to the y-axis.

Therefore the coordinates of the point shown are (6, 8).

The rate of change of a linear function is the slope.

The slope-intercept form of a linear function is:

  • y = mx + b
    (where m is the slope and b is the y-intercept).

Given function: y = -x + 5

The given function is in slope-intercept form.

Therefore, the rate of change (slope) of the function is -1

Given function: y = 17.5x + 19

The given function is in slope-intercept form.

Therefore, the rate of change (slope) of the function is 17.5

Store A

9 bottles of apple juice = $2.79

⇒ 1 bottle of apple juice = $2.79 ÷ 9 = $0.31

Store B

18 bottles of apple juice = $16.74

⇒ 1 bottle of apple juice = $16.74 ÷ 18 = $0.93

To calculate how much less a bottle of apple juice at Store A is than at Store B, subtract the cost of one bottle of apple juice at Store A from the cost of one bottle of apple juice at Store B:

⇒ $0.93 - $0.31 = $0.62
