Sheila gathered data about the minutes she played and the points she scored in eight recent basketball games. The data and the line of best fit are shown in the scatter plot. The equation of the line of best fit is y = 0.422x − 1.528. Could this line of best fit be used to make reasonable predictions?

you need to show the graph

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.

it would open into a square depending on the type of envelope i’m not sure about the second part
