for a linear function the slope is the rate of change of the dependent variable as the independent variable changes. The change in y /corresponding change in x
given 2 points (x1, y1) and (x2, y2) the rate of change is (y2 - y1)/(x2 - x1)
sometimes this is referred to as rise/ run
for this problem find 2 points on the line and use the formula
the y is the change in volume as x the length changes
OpenStudy (triciaal):
here the slope is 9/3 = 3

The answer is 3? or 9/3 ?
OpenStudy (triciaal):
3

Thank you so much !!

pick 2 different points (1,3) and (2, 6) slope would be y2 - y1/x2- x1 = 6 -3/ 2 - 1 = 3/1 = 3

Thank you . That helped alot :)

do you understand what it is and how to find the slope now?
OpenStudy (anonymous):
Yes I do. Thank you
