Any straight line on the coordinate plane can be described by the equation
y=mx+b
Where:
x,y are the coordinates of any point on the line
m is the slope of the line
b is the intercept (where the line crosses the y-axis) .
The slope m can be found beetween two points on the line:
and
In this case, the points is on the y-axis (0,300) and the x-axis (450,0), whereby the slope m is found:
We already have b, because b is the point, where the line crosses the y-axis.
b=300
So the equation is:
⇒
The graph is attached.
