Is this asking for the slope?
Y=-10x+60
You do rise/run which is -20/2, so -10
Then just find the y-intercept, which is 60.
It will be B (I had this question before)
Based on the formula given for the model of the average cost of tuition and fees, the average cost of tuition in 2010 was $25,858.
<h3>What was the average cost of tuition at private colleges in 2010?</h3>
The base year is 2000 and x denotes the number of years after 2000.
The value of x for 2010 is therefore:
= 2010 - 2000
= 10 years
The average cost of tuition in 2010 is therefore:
= 26 (10)² + 814(10) + 15,118
= 2,600 + 8,140 + 15,118
= $25,858

This is sometimes true because when distributing the sign could either be either minus or plus...
If you multiply a positive number with a negative number it will be negative. If you multiply a negative by a negative it will be positive. If you multiply a positive with a positive it will be positive.
Radii is defined as the line joining the centre of the circle to a point on the circumference
as there are infinite points on a circle
therefore there are infinite number of radii and hence there is no fixed number.
