Question 55068
Let's find two arbitrary solutions for the equation. When x = 0, y = 2 (3/4 of 0 is 0). When x = 4, y = {{{3*4/4 + 2 = 5}}}. Now we know that points (0, 2) and (4, 5) are solutions. In the graph, we connect these two points and we have a line!

{{{graph(600, 600, -10, 10, -10, 10, 3x/4 + 2)}}}
