Question

What is the slope of the line that
passes through the points (-1, 3)
and (2, 10)?

Answer 1

D
`(7)/(3)`

Explanation:

For find the slope of whatever line we use the next formula:

`m = (\Delta y)/(\Delta x) = (y_2 - y_1)/(x_2 - x_1)`

So in our occasion we have:

`y_2 = 10 \quad \text{and} \quad y_1 = 3\\x_2 = 2 \quad \text{and} \quad x_1 = -1`

Replacing in the equation:

`(10 - 3)/(2 - (-1)) = (7)/(3)`

So the answer is
`(7)/(3)`
