what is the equation of a line including (4,7) and (0,7)

OpenStudy (anonymous):

First use the points to find the slope. \[m=(y2-y1)/(x2-x1)\] Then use the slope-intercept form (y=mx+b) with the slope you found (m) and one of the given points to find the y-intercept (b).

what would be 4/0 would that just be 4?

jimthompson5910 (jim_thompson5910):

You have it the other way around kaylie17

jimthompson5910 (jim_thompson5910):

It should be 0/4

OpenStudy (anonymous):

so would that be 4?

jimthompson5910 (jim_thompson5910):

no, you have 0 items and you're dividing those 0 items among 4 friends...how many items does each friend get?

OpenStudy (anonymous):

0 divided by anything is...?

OpenStudy (anonymous):

You also need to be careful. 0 - 4 = -4, not 4.
