Question

Right in equation in slope intercept form of the line that passes through the points (4,2) and (1, -7)

Answer 1

Step-by-step explanation:

Slope-intercept form: →
`y=mx+b`

m: represents the slope and is constant.

b: represents the y-intercept.

You can also to used rise/run.

`(rise)/(run)`

`m=(rise)/(run)`

`Slope=(y^2-y^1)/(x^2-x^1)`

`(x^1, y^1)=(4,2)`

`(x^2, y^2)=(1, -7)`

`rise=y^2-y^1=-7-2=-9`

`run=x^2-x^1=1-4=-3`

You can also divide into the -3 are:

`-9/-3=3`

But the slope is 3.

But the y-intercept is -3.

Hope this helps!

Thanks!
