in the set (7,0) the 7 represents an x and the y a 0

and in the set (0,1) the 0 represents x and 1 represents y

The slope is the the first y subtracted from the second y OVER the first x subtracted from the second x.

Example:

Find the equation of the line that passes through the points

(-2, 4) and (1, 2).

slope (m) = 4-2 / (-2 -1)

Well, if I have two points on a straight line, I can always find the slope; that’s what the slope formula is for.

Now I can solve for b

I can do this by picking either set and plugging it ionto the equation. I am going to use (-2,4).

4=(my slopewhich is) -2/3x+ (-2)

now I have my b value by solving this equation. b= 8/3

NOw I have all the infor I need to write in slope intercept.

y= -2/3 x + 8/3.

Follow the same steps for your problem and you should do just fine!

L:et me know if you need more help

Math Doesn’t Suck — is written by the girl on Boy Meets World T V show as she brillinat at math and want girl and boys to undedstand math better.

The problem: both the (7) and the (1) are postive number so your line will be on a downward slope from 1 on the y to the 7 on the x.

Hope this helps

ps i think you use the formula ?=mx+c
