Question

Which pair of points have a slope of -3/5?

A (4, 0), (-2, 10)

B (10, -2), (0, 4)

C (4, 2), (10, 4)

D (-4, -10), (0, -2)

Answer 1

No of these answers has a slope of
`(-3)/(5)` . My guess is B becasue its close to
`(-3)/(5)` unless the 5 is supposed to be negative

Explanation:

You have to use the slope formula
`(y_(2) - y_(1) )/(x_(2) - x_(1) )`

(
`x_(1)`,
`y_(1)`), (
`x_(2)`,
`y_(2)`)

(4, 0), (-2, 10)
`(10 - 0 )/(-2 - 4 )= (10)/(6)` you have to simplfy, the answer will be
`(5)/(3)`

(10, -2), (0, 4)
`(4 - -2 )/(0- 10 )= (6)/(-10)` you have to simplfy, the answer will be
`(3)/(-5)`

(4, 2), (10, 4)
`(4 - 2 )/(10 - 4 )= (2)/(6)` you have to simplfy, the answer will be
`(1)/(3)`

(-4, -10),(0, -2)
`\frac{{-2- -10} }{0 - -4 }= (8)/(4)` you have to simplfy, the answer will be
`(2)/(1) =2`
