Use the image to answer the question.
An illustration shows a coordinate plane with 4 quadrants. The x-axis ranges from negative 9 to 9 in one unit increments, and the y-axis ranges from negative 11 to 11 in one unit increments. A line is graphed on the plane. An upward slanting line passes through points plotted at left parenthesis 3 comma 1 right parenthesis, left parenthesis 6 comma 2 right parenthesis, and left parenthesis 9 comma 3 right parenthesis.
Write the equation of the line y=mx through the origin that describes the proportional relationship shown in the graph.

what is the unit cost from the graph
To determine the equation of the line y=mx through the origin, we need to find the slope of the line. The slope (m) can be calculated using the formula:
m = (change in y) / (change in x)
By looking at the graph, we can see that the change in y is 1 and the change in x is 3 for each point. Therefore, the slope is:
m = 1 / 3
The equation of the line y=mx through the origin can be written as:
y = (1/3)x
my bad this was for a different question
thx!

hi
Since the line passes through the origin, the y-intercept is 0.
To find the slope, m, we can use the formula:
m = (change in y / change in x)
From the given points, we can see that the change in y is 1 and the change in x is 3.
So,
m = 1/3
The equation of the line y=mx is y = 1/3x.
