Question

What is the slope of the line shown below?

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

Answer 1

A

Explanation:

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

The slope of the line can be calculted using formula

`(y_2-y_1)/(x_2-x_1).`

Thus, the slope of the given line is

`(1-(-7))/(9-(-3))=(8)/(12)=(2)/(3).`

Answer 2

A

Explanation:

slope is given by the formula:

`(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:

`(1--7)/(9--3)\\=(1+7)/(9+3)\\=(8)/(12)\\=(2)/(3)`

correct answer is A
