Find the function rule, show all work.

y = -5x - 1

Step-by-step explanation:

Note that as x increases from -2 to -1, y decreases from 9 to 4, a drop of 5.

Similarly, if x increases from 0 to 1, y decreases from -1 to -6, a drop of 5.

Thus, this table represents a decreasing linear function.

The slope of this line is m = rise / run = -5 / 1, or just -5.

Using the point-slope formula for the equation of a straight line:

y -k = m(x - h).  Here, the slope, m, is -5, and one point on the line is (0, -1).

Thus, we have y + 1 = -5(x - 0), or y = -5x - 1.

The "function rule" here is y = -5x - 1, a linear function.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
