Select the table that shows propernal function

Reasoning:

Every direct proportional function always goes through the origin (0,0). In other words, the y intercept is always 0.

Choices B, C, and D can be ruled out because their y intercepts are nonzero (eg: choice D has a y intercept of 10).

With choice A, the point (0,0) is on the graph. So far, so good. Notice that dividing each pair of nonzero x,y values leads to the same result.

This suggests that the constant of proportionality is 10, and that the equation for table A is y = 10x. Any direct proportion equation is of the form y = kx, with k being the constant of proportionality. To find k, we can write k = y/x where x,y are nonzero.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
