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 equation of the line passing through the points (1, 5) and (2, 10), we first need to find the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1)
Where (x1, y1) = (1, 5) and (x2, y2) = (2, 10)
m = (10 - 5) / (2 - 1)
m = 5 / 1
m = 5
Therefore, the slope of the line is 5.
Since the line passes through the origin, the equation of the line will be in the form y = mx.
Substitute the value of m into the equation:
y = 5x
Therefore, the equation of the line passing through the origin is y = 5x.

A coordinate plane ranges from negative 9 to 9 in unit increments on the x-axis and from 11 to negative 11 in unit increments on the y-axis. A line with arrows at both the ends joins three plotted points and extends beyond. The coordinates of the plotted points are: left parenthesis 0 comma 0 right parenthesis, left parenthesis 1 comma 3 right parenthesis, and left parenthesis 2 comma 6 right parenthesis.
