Question

if a line passes through the points (20,5) and (10,10), then the slope of the line is 1/2. a. true b. false

Answer 1

b false

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (20, 5 ) and (x₂, y₂ ) = (10, 10 )

m =
`(10-5)/(10-20)` =
`(5)/(-10)` = -
`(1)/(2)`
