Answer:
The equation that closely represents the graph is
Option A is correct.
Step-by-step explanation:
We need to find equation that represents the graph.
We can write equation in slope-intercept form: where m is slope and b is y-intercept.
For finding the equation we need to find slope and y-intercept
Finding slope
The slope can be found using formula:
From the graph we can find
Putting values and finding slope
We get Slope = 60
Finding y-intercept
Using point (0,-160) and slope m = 60, we can find y-intercept
Writing the equation
So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:
So, The equation that closely represents the graph is
Option A is correct.
