Explanation:
The graph of y = -3/5x + 9 is a straight line, so to graph the function we need to identify two points of the line.
Then, we can find two points if we give a value to the variable x and calculate the value of y as:
If x = 5 then:
y = (-3/5)x + 9
y = (-3/5)*5 + 9
y = -3 + 9
y = 6
If x = 10 then:
y = (-3/5)*10 + 9
y = -6 + 9
y = 3
Therefore, we have the points (5, 6) and (10, 3), so the graph of the line is:
