Question

A line in the Cartesian plane passes through the points ( 5,8) and (9, 15) . What's the slope of the line? A. 4/7 B. 7/4 C. - 4/7 D. -7/4

Answer 1

B. 7/4

Explanation:

To find the slope of the two points (5,8) and (9,15) we have to use the slope formula

`slope=(y_(2)- y_(1) )/(x_(2) -x_(1) )`
`slope=(15-8)/(9 -5)`

`slope=(7)/(4)` can also be written as a decimal
`slope=1.75`
