Answer:
y = ⅗x
Explanation:
The line passes through the point of origin, (0, 0). This implies that the graph represents a proportional relationship between x and y. Thus, in slope-intercept form, the line of a proportional graph can be represented as y = mx.
Where,
m = slope/constant of proportionality = y/x
To write an equation for the line, let's find the slope using any of the points on the line.
Using (50, 30):
Slope (m) = 30/50 = ⅗
Plug in the value of m into y = mx
Thus, equation of the line would be:
y = ⅗x
