Please help I learned this a while ago and forgot how to do it

The slope-intercept form is

Step-by-step explanation:

To find the slope, use

Replace the x and y values with the points.

Solve.

After that, find the y-intercept form.

Put the equation in point-slope form.

Replace x with 0.

Add 5 to both sides.

Convert to improper fraction form.

The y-intercept is

Now finally, write in slope-intercept form. (y=mx+b)

m is slope, b is the y-intercept.

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.
