Question

Find the value of y so that the line passing through the two points have the given slope (2,3) (7,y) m=-2/5

Answer 1

y = 1

Explanation:

Find the slope of the line passing through the points
`(2,3)` and
`(7,y):`

`m=(y-3)/(7-2)=(y-3)/(5)`

The slope of the line is equal to

`m=-(2)/(5),`

then

`(y-3)/(5)=-(2)/(5)\\ \\y-3=-2\\ \\y=-2+3\\ \\y=1`
