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 5 right parenthesis and left parenthesis 2 comma 10 right parenthesis.
The graph shows the proportional relationship. Derive the equation of the line y=mx through the origin.

____
To find the slope (m) of the line, we can use the formula:
m = (y2 - y1) / (x2 - x1)
m = (10 - 5) / (2 - 1)
m = 5 / 1
m = 5
Since the line passes through the origin, the equation of the line in slope-intercept form (y = mx) would be:
y = 5x
