<h2>Explanation:</h2>In this exercise, <em>we have the following points:</em>
And <em>the following linear equations:</em>
When plotting these graphs, we find the following facts:
<h3>For (1):</h3>We see the graph in the first figure below. The graph only passes through the point (0, 8)
<h3>For (2):</h3>This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)
<h3>For (3):</h3>This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)
<h3>For (4):</h3>This is the fourth graph below. The graph only passes through the point (0, 8)
So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>

Answer:
r = -6
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope and b is the y-intercept.
Slope 3/4
This means that , and thus:
(6,3)
This means that when . We use this to find b. So
So
(-6, r)
r is y when . So
So r = -6.
