With the ordered pairs (5,2) (6,4), 4 is y sub 2, 2 is y sub 1, 6 is x sub 2, 5 is x sub 1. So you would do 4-2 over 6-5 to find the m. So your m would equal 2 over 1, which would equal 2. You now have your m. To find the b, you substitute one of the ordered pairs (it doesn’t matter which one) into the equation. I’ll do the first one:

2=2(5)+b

2=10+b

subtract 10 from both sides to get b by itself

-8=b

so your slope-intercept equation would be:

y=2x-8

Good luck!

The number before the x is always the slope.

The number after the + is always the y intercept.

(4 is the same as 4/1 and its go up the top number/go over the bottom number)

so you put the first point at 7 on the y axis, then go up 4 and over 1 space and put the point there. Draw a line between the 2 points and that is the line.
