Question

A line is drawn so that it passes through the points (-7,0) and (9,4). What is the slope of the line? Round the answer

to the tenths place. If the answer is a whole number than make the tenths place a zero to be counted as correct.
Your Answer:

Answer 1

Answer: The slope of the line is approximately 0.3.

Explanation

First, plug in the coordinates in the slope formula:

m =
`(y_(2) - y_(1) )/(x_(2) - x_(1) )`

m =
`(4 - 0)/(9 - (-7))`

Simplify:

m =
`(4 - 0)/(9 - (-7))`

m =
`(4)/(16)`

m =
`(1)/(4)`

Write as a decimal:

m =
`(1)/(4)`

m = 0.25

Round to the nearest tenth:

m ≈ 0.3
