Find the equation of the line. Use exact numbers.

Question

on a graph need help plz

Answer 1

In slope-intercept form, the equation of a line looks like:   y = mx+b

                where m is the slope      and b is the y-intercept

 

Here is one method:   determine the slope and the y-intercept

     Using any two points on the line, the slope is:

             m = (difference in y values) / (difference in x values)

     The y-intercept is the point where x=0  [that is, the line crosses the y-axis at the point (0,b)]
