Homework Statement


suppose you had the points (7,1) and (3,10)


Homework Equations



i know that Y2- Y1/X2 - X1 give you the slope

The Attempt at a Solution


please help this problem is killing my math grade on tests thank you

Ok, you have the slope. What is it? The y-intercept form is y=m*x+b where m is the slope. To find b, put one of your points into the equation, say x=7, y=1 and solve for b.
 
This part is wrong. Do you know how to correct this:
2. Homework Equations

i know that Y2- Y1/X2 - X1 give you the slope
Either use a good mathematical typesetting system, such as Tex or TexAide, or write the formula for slope properly using grouping symbols:
(Y2 - Y1)/(X2 - X1)
 
oh... thank you i feel silly now and sry bout the incorrectness i have never posted in math/science help forums before
