Question

??????????help pls?????

Answer 1

Answer: 0.5

Explanation:

Given

Line passes through
`(-10,-30), (0,-25), (10,-20), \text{and}\ (20,-15)`

The slope of the line is

`m=(y_2-y_1)/(x_2-x_1)`

Taking any two points: (0, -25) and (20,-15)

Slope is

`\Rightarrow m=(-15-(-25))/(20-0)=(10)/(20)\\\\\Rightarrow m=0.5`
