you use this equation to find the y int
where b is the y int
and m is the slope.

step 1:
find the slope

to do this you will need 2 points.
(1,8)(2,6)
put these points into the following equation

The slope or m is -2.

step 2:
find b

once givce the slope, you now have

using a point
(1,8)
you can find b

since b is the y int, the y int is 10 or (0,10)

You can pick any 2 points, find the equation, then find the y-intercept.

Or, you can see from this pair
1 8
2 6
that y increases 2 when x decreases by 1
Subtract 1 from x --> add 2 to y.
--> (0,10)
