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 1 comma 4 right parenthesis and left parenthesis 2 comma 8 right parenthesis.

Find the equation of the line y=mx through the origin that describes the proportional relationship shown in the graph.

To find the equation of the line, we need to determine the slope, m.

The slope is determined by the change in y divided by the change in x. It can be calculated using the coordinates of the two points (1,4) and (2,8):

m = (8 - 4) / (2 - 1)
m = 4 / 1
m = 4

So, the equation of the line y = mx through the origin is y = 4x.

Apologies for the incorrect previous response.

To find the equation of the line, we need to determine the slope, m.

The slope is determined by the change in y divided by the change in x. It can be calculated using the coordinates of the two points (1,4) and (2,8):

m = (8 - 4) / (2 - 1)
m = 4 / 1
m = 4

Thus, the slope of the line is 4.

Since the line passes through the origin (0,0), the equation of the line y = mx through the origin is y = 4x.
