i was given (.5, 2/3)
how do i find that slope?
2007-03-20 14:30:00 · update #1
Ok I know how to do this, so Trust me!
First find the slope between the two points.
The formula for slope rise/run. = y2- y1 over x2 -x1
plug in your x and y values from your two points, the y's from each of them into the y2 and y1. And your x's accordingly.
Then use point slope form to find your equation.
this equation is : y - y1 = m(x - x1)------m is slope.
Then plug is your slope and one of your points and solve for y.
Good luck!

The equation of a line is y=mx+b. If the line passes through the origin, then b is 0. To find m, you need to use the slope formula.
m= (y2 - y1) divided by (x2 - x1)
It doesn't matter which point is P1 or P2.
Tell us what the points are, and we might be able to help you more.

find the slope (change in y divided by change in x).
using the formula y=mx+b, where m is the slope and b is the y intercept, your equation should just be y =mx since b is 0 (the origin is (0,0).

first find the slope (rise/run)
then use equation y=mx+b
m=slope; x&y=coordinates other than origin; solve for b
then just plug m and b into above equation
