Question

the table of values shows a linear relationship between x and y. what is the slope of the line represented by the table of values? x is -7,-2,3,8 and y is 9,1,-7,-15

Answer 1

Explanation:

To find the slope of the line represented by the table of values, we need to use the formula:

slope = (change in y) / (change in x)

We can choose any two points from the table to calculate the slope. Let's choose the first and last points: (-7, 9) and (8, -15).

change in y = (-15) - 9 = -24

change in x = 8 - (-7) = 15

slope = (change in y) / (change in x) = -24/15 = -8/5

Therefore, the slope of the line represented by the table of values is -8/5.
