Question

What is the slope of the line that contains the points (−3, −1) and (3, 8)?

two thirds
three halves
Undefined
0

Answer 1

m =
`(3)/(2)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 3, - 1 ) and (x₂, y₂ ) = (3, 8 )

m =
`(8-(-1))/(3-(-3))` =
`(8+1)/(3+3)` =
`(9)/(6)` =
`(3)/(2)`

Answer 2

3/2

Explanation:

To find the slope, we use the slope formula

m = ( y2-y1)/(x2-x1)

= (8- -1)/( 3 - -3)

= (8+1)/(3+3)

= 9/6

= 3/2
