Use your graph to estimate solutions to the equation x2-2x-1=0

There are 2 real solutions to the equation.  Evaluate  the discriminant = 8.             Using the quadratic formula = What is on the picture.

6

Step-by-step explanation:

In the slope- intercept form (y= mx +c), the slope is the coefficient of x.

Let's rewrite the given equation into the slope- intercept form.

6x -y= 1

6x= y +1

y +1= 6x

y= 6x -1

Since the coefficient of x is 6, the slope of the given line is 6. Parallel lines have the same slope and thus the slope of the line parallel to the given line is also 6.
