Answer:
The line passing through the given points is:
in its slope-intercept form
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points using the slope formula:
which for our case renders:
Now we can find the y-intercept by using any one of the given points in the general slope-intercept form of a line with this slope:
Therefore, the equation of the line becomes:
Well first you have to find the solution, before you can put it in RADICAL FORM
Answer:
$14.40

(240+80)/5 = 320/5 = 64
Her avg is 64 (c).
