Answer:
[tex]y = 120x [/tex]
Step-by-step explanation:
Equation of a straight line is
[tex]y = mx + b[/tex]
m= slope of line = rise/run which can be computed by taking two points on the line, finding the difference I the y coordinate values and dividing by the correspoding difference in their x coordinate values
b is the y-intercept where the line crosses the y-sxis
Looking at the graph we can see that the line crosses the y-sxis at the origin (0, 0) so the y-intercept is at y=0
The slope is determined by examining the two highlighted points (3, 360) and (2, 240)
Slope =
[tex] \frac{360 - 240}{3 - 2} = \frac{120 }{1} = 120[/tex]
So equation of line is
[tex]y = 120x + 0[/tex]
or
[tex]y = 120x[/tex]
