Write the equation of the line y=mx through the origin that describes the proportional relationship shown in the graph. (1 point)
point 1:(3,1)
point 2:(6,2)
point 3:(9,3)
To find the equation of the line y = mx through the origin, we need to find the slope (m).
First, let's find the slope between point 1 and the origin:
m = (y2 - y1) / (x2 - x1)
= (1 - 0) / (3 - 0)
= 1 / 3
Since the line passes through the origin, the y-intercept (b) is 0.
Therefore, the equation of the line is y = (1/3)x.
