Question

Help please I don’t know please

Answer 1

Answer:

$-\frac{3}{10}$

Step-by-step explanation:

Slope is the change in y coordinates by change in x coordinates.

Or  $m=\frac{\delta y}{\delta x}$

Looking at the table, the change in each value of x is 10 (10 to 20 to 30 to 40).

Also, the change in each valueof y is -3 (20 to 17 to 14 to 11).

Note: change in y is negative since it is DECREASING.

Hence the slope would be -3/10
