The points in the table lie on a line. Find the slope of the line.

Wewaii [24]

Answer:

$Slope (m) = -\frac{3}{4}$

Step-by-step explanation:

Using any two pairs from the table of values given, (-2, 5) and (2, 2):

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

Where,

$(-2, 5) = (x_1, y_1)$

$(2, 2) = (x_2, y_2)$

Plug in the value into the slope formula:

$Slope (m) = \frac{2 - 5}{2 -(-2)}$

$Slope (m) = -\frac{3}{4}$
