7x - 9 < 12
7x < 12 + 9
7x < 21
x < 21/7
x < 3
1/4x + 8 > 11
1/4x > 11 - 8
1/4x > 3
x > 3 * 4
x > 12
solution : x < 3 or x > 12
To plot more the points, we move up one and right two.
<h3>How to plot more the points?</h3>
The ratios are given as:
(1, 0.5), (2, 1), and (5, 2.5)
Calculate the slope (m) using:

So, we have:

Evaluate

This gives

The above means
Vertical : Horizontal = 1 : 2
This means a vertical movement of 1, followed by an horizontal movement of 1
Hence, to plot more the points, we move up one and right two.

Complete question
Three equivalent ratios are shown on the graph. On a coordinate plane, points (1, 0.5), (2, 1), and (5, 2.5) are plotted. Starting on one of the plotted points, how can you plot more equivalent ratio points?
The property is product which is multiplication
It's f(x) = sin2x
Because when you multiply x by any number greater than 1, the graph will shrink.
Try but pi/2 in the equation you will get sin(pi) which is 0. And that satisfies the gragh.
