Need help with math bell ringer

Answer 1

y = 2

Explanation:

Slope that passes through two points, (10, y) and (3, 4) =
`m = (y_2 - y_1)/(x_2 - x_1)`.

Where,

`(10, y) = (x_1, y_1)`

`(3, 4) = (x_2, y_2)`

m = -²/7

Plug in the values

`(-2)/(7) = (4 - y)/(3 - 10)`

`(-2)/(7) = (4 - y)/(-7)`

Cross multiply

`-2*-7 = 7(4 - y)`

`14 = 28 - 7y`

`7y = 28 - 14`

`7y = 14`

Divide both sides by 7

y = 2
