Question

Pleaes help me. The points in the table lie on a line. Find the slope of the line.

0/1/2/3
-1/0/1/2

Answer 1

slope = 1

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (3, 2) ← 2 ordered pairs from the table

m =
`(2-(-1))/(3-0)` =
`(2+1)/(3)` =
`(3)/(3)` = 1
