Question

What is the slope of the line shown below?

A. 2/3
B. -3/2
C. 3/2
D. -2/3

Answer 1

Answer:

A

Step-by-step explanation:

The line passes through the points (-3,-7) and (9,1).

The slope of the line can be calculted using formula

$\dfrac{y_2-y_1}{x_2-x_1}.$

Thus, the slope of the given line is

$\dfrac{1-(-7)}{9-(-3)}=\dfrac{8}{12}=\dfrac{2}{3}.$

Answer 2

Answer:

A

Step-by-step explanation:

slope is given by the formula:

$\frac{y_2-y_1}{x_2-x_1}$

We need 2 points to find a line's slope.

• The first point is (-3,-7) hence x_1 = -3 & y_1 = -7.
• The second point is (9,1) hence x_2 = 9 & y_2 = 1.

Plugging these into the slope formula, we will get the slope:

$\frac{1--7}{9--3}\\=\frac{1+7}{9+3}\\=\frac{8}{12}\\=\frac{2}{3}$

correct answer is A
