To find the slope (m) of the line that represents the proportional relationship between the points (3,1), (6,2), and (9,3), we can use the formula:
m = (y2 - y1) / (x2 - x1)
Using the points (3,1) and (6,2):
m = (2 - 1) / (6 - 3)
m = 1 / 3
Therefore, the slope (m) is 1/3. Since the line passes through the origin (0,0), the equation of the line is:
y = (1/3)x
So, the equation of the line that describes the proportional relationship shown in the graph is y = (1/3)x.
write the equation of the line y=mx through the origin that describes the proportional relationship shown in the graph
