5. the table shows the water level of (ft) of a pool with a leak after x hours, when this data are graphed on a coordinate grid the points all lie on the same line what are the slope and y interception of this line?

  A.  Slope = -0.4, Y-intercept = 6.4 ft

The "hours" numbers in the table are all 1 unit apart, so the difference of any adjacent "level" numbers is the slope:

  (5.6 ft - 6 ft)/(2 h -1 h) = -0.4 ft/h . . . . . the slope

Backing that up one hour to 0 hours, we would add 0.4 to the level at 1 hour:

  6 ft + 0.4 ft = 6.4 ft . . . . . . level at 0 hours (the Y-intercept)

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
