Answer 2

For this case we have that by definition, the slope of a line is given by:

`m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}`

We have as data that:

`m = -2\\(x_ {1}, y_ {1}) :( 3,5)\\(x_ {2}, y_ {2}) :( 4, y)`

Substituting we have:

`-2 = \frac {y-5} {4-3}\\-2 = \frac {y-5} {1}\\-2 = y-5\\-2 + 5 = y\\y = 3`

Finally, the value of y is 3.

Answer:

`y = 3`
