Question

Help find y .. slope is m=-5/8

Answer 1

y = 8

using the ' gradient formula' m = (y₂ - y₁)/(x₂ - x₁)

with (x₁, y₁) = (3, 3), (x₂, y₂) = (- 5, y) and m = -
`(5)/(8)`

(y - 3)/( - 5 - 3) = -
`(5)/(8)`

(y - 3)/(-8) = -
`(5)/(8)`

multiply both sides by - 8 to eliminate fractions

y - 3 = 5

add 3 to both sides

y = 5 + 3 =8
