@watermelon16 can u help?
OpenStudy (anonymous):
Yes sorry... I left my computer for a moment. Have you learned to find the slope of the line or anything yet?
OpenStudy (anonymous):
you only need 2 points to find the equation. and use other points to test out your result..

equation of a line is in the form y = mx + b
OpenStudy (anonymous):
where m is a slope and b is a constant.
OpenStudy (anonymous):
you find m by this formula : m = (y2-y1)/(x2-x1) with 2 points (x1,y1) and (x2,y2)
OpenStudy (anonymous):
pick 2 points (x1,y1) and (x2,y2) from your table there, tell me what is the slope m with that formula ?
OpenStudy (anonymous):
Do you understand how to do it?
