Question

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

Answer 1

Answer:

D  $\frac{7}{3}$

Step-by-step explanation:

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

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

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:

$\frac{10 - 3}{2 - (-1)} = \frac{7}{3}$

So the answer is $\frac{7}{3}$
