Since the line passes through the origin and the points (3, 3) and (8, 8), we can see that the equation of the line is y = mx.
Using the points (3, 3) and (8, 8):
3 = m(3)
8 = m(8)
From the first equation, we find that m = 1.
Therefore, the equation of the line is y = 1x, which simplifies to y = x.
Use the graph to derive the equation y=mx for a line through the origin. Simplify the numerical coefficient, if needed.
y=3x
y=3/3x
y=8x
y=x
Points on the graph: 3, 8
