Answer:

The slope of line is 9

Step-by-step explanation:

We can use two pairs of input-output from the table to find the slope of the given line. Here x is input and y is output.

Slope is defined as the steepness of a line and is given by the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Selected pairs from table are:

(-1,-18) and (0,-9)

Here

$x_1 = -1\\x_2 = 0\\y_1 = -18\\y_2 = -9$

Putting the values in the formula

$m = \frac{-9-(-18)}{0-(-1)}\\=\frac{-9+18}{0+1}\\= 9$

Hence,

The slope of line is 9
