question 9 of 10\nwhat is the slope of the line shown below?\n(4, 8)\na. -1/3\n(2, 2)\nb. 1/3\nc. -3\nd. 3

Answer:

D. 3

Explanation:

Step1: Recall slope formula

The slope ( m ) between two points ((x_1, y_1)) and ((x_2, y_2)) is ( m=\frac{y_2 - y_1}{x_2 - x_1} ).

Step2: Identify the two points

The two points on the line are ((2, 2)) and ((4, 8)). Let ((x_1, y_1)=(2, 2)) and ((x_2, y_2)=(4, 8)).

Step3: Substitute into the formula

Substitute the values into the slope formula: ( m=\frac{8 - 2}{4 - 2}=\frac{6}{2}=3 ).
