Question

What si the equation in slope intercept form of the line that passes through the points (-4,2) and (12,6)

Answer 1

b = -12

Explanation:

In order to find the slope intercept you must first find the slope of the given points.

`-4,2 = 12,6`

`S=(y2-y1)/(x2-x1)`

Substitute:

`(12--4)/(6-2)`

`12--4=12+4=16`

`6-2=4`

`S=(16)/(4)`

Now find the slope intercept

`16/4=4`

`SI=y=mx+b`

Substitute:

`12=4*6+b`

Solve:

`4*6=24`

`12=24+b`

Subtract 24 on both sides:

`12-24=-12`

`x=-12`

`y=-12`

Hope this helps.
