Question 49884: how do you get the equation from a line?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! The equation of a line can be written in the form y = mx+b. To find the equation of a line, you have to find the values of m and b.
First make note of the y intercept, which is where the graph crosses the y axis. This value of y is b.
Next, find any two points on the graph and measure the rise and the run between these two points. The rise over the run is the slope, so this ratio will be the value of m.
Last, substitute these values of m and b back into the formula y = mx+b.
