Answer:
the slope would be equal to -x or -1
Step-by-step explanation:
First rewrite the equation in correct slope intercept form. Subtract x from both sides and then divide both sides by a negative sign.
x - y = 8
-x -x
y= x +8
A perpendicular slope is the inverse of the original slope. If the original slope is 2 then the perpendicular slope would be -1/2. In this problem the original slope is 1. The inverse of 1 is -1
For this case we have that by definition, the quadratic formula is:
A quadratic equation is of the form:
Option A: This equation can be solved without the quadratic formula
Option B:
This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.
Option C:
Similarly, this equation can be solved with the quadratic formula
Option D:
In this factored equation we can see that the roots are
Answer:
Option B, C
