Answer:
y = 1/5x
Step-by-step explanation:
Plot the points.
We connect them to make a line.
line equation:
y = mx + b
First, we find the slope of the line.
Two points are already given.
(15,3) (0,0)
Slope formula:
m = y₂ - y₁ / x₂ - x₁
m = 0 - 3 / 0 - 15
m = -3 / -15
m = 1/5
If we use that slope on the graph.
We can already see the y-intercept (even without a graph).
It passes at point 0.
So the equation of the line is:
y = 1/5x
