Which ordered pair is a solution to this equation? 2x - 9y = 38 (7, 5) (4, -1) (3, -3) (1, -4)

To solve this problem, we can simply substitute in the coordinate values for and in the equation:

First ordered pair

The first ordered pair is not the answer.

Second ordered pair

The second ordered pair is not the answer.

Third ordered pair

The third ordered pair is not the answer.

Fourth ordered pair

The fourth ordered pair is the solution.

The solution is the fourth ordered pair.

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
