What happens when you know the slope, the y-intercept, and 2 different points. The teacher needs it in standard form, but I dont know how to? How am I supposed to write it in standard form? m = -2 b = 12 point 1 (2,8) point 2 (6,0)

We aren't given the y-intercept, so the easiest way would be to pick one of the points and toss all that into a point slope form and then convert to standard.

(y - 8) = -2(x - 2)
y - 8 = -2x + 4
2x + y - 8 = 4
2x + y = 12

or with the other point:

(y - 0) = -2(x - 6)
y = -2x + 12
2x + y = 12

As you can see they both reach the same results, as would any other point on the same line

From above data we can calculate the equation of line in two different ways

general form of equation of line

y=mx+c
y=-2x+12

or when two points are given then general form of equation of line:

(y-y1)=((y2-y1)/(x2-x1))*(x-x1)

(y-8)=((0-8)/(6-2))*(x-2)
y=-2x+12



I am a cool guy and i love people by helping them....
