Question

2. a. Calculate the slope of the lines. 4 2 1 (0,3) 1 2 (4,1) 3 4 5 6 I​

Answer 1

slope = -
`(1)/(2)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 1) ← 2 points on the line

m =
`(1-3)/(4-0)` =
`(-2)/(4)` = -
`(1)/(2)`
