The scatterplot shows how many pass attempts and yards a quarterback has in different football games. Notice that the line passes through the second point from the left, (24, 127) and the farthest point on the right (36, 163).

What is the slope of the trend line?

Given:

Given that the points in the scatter plot. The line passes through the second point from the left (24,127) and the farthest point on the right (36,163)

We need to determine the slope of the trend line.

Slope:

The slope of the trend line can be determined using the formula,

Substituting the coordinates (24,127) and (36,163) in the above formula, we get;

Simplifying, we get;

Thus, the slope of the trend line is 3.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
