Table

Hours 2 4 6 8

Water remining 43 36 29 22

If you calculate the change in water remaining / hours elacpse you ge a constant value:

[36-49]/[4-2] = [29-36]/[6-4-29] = [22-29] / [8-6] = -7/2 = - 3.5

That is the slope.

The y-intercept is y when x =0, this is the volume of water when time is 0.

You can calculate it by adding 7 to 43 = 43 + 7 = 50

Then, the equation is y = -3.5x + 50
