Question

The ordered pairs (20, -29.5),(21, -31), and (22, -32.5) are points on the graph of a linear equation. Which
of the following graphs show all of the ordered pairs in the solution set of this linear equation?

Answer 1

The graph that contains the 3 points is the bottom right graph.

Which line contains the 3 points?

We want to see which of the graphs contains the 3 ordered pairs:

(20, -29.5),(21, -31), and (22, -32.5)

So we just need to look at the graphs and see which one has these points, notice that as x increases y decreases, so we have a decreasing line.

The slope of the decreasing line is:

a = (-31 + 29.5)/(21 - 20) = -1.5

The graph with this slope is the last one (bottom right, the other decreasing line has a slope of -1). So that is the correct option.
