Answer:
-4
Step-by-step explanation:
It the slope hits the y axis, that number will be the y intercept
Answer:
The solution is
. Fourth option
Explanation:
Solve for x:

Move all the terms from the right to the left side of the equation, a zero in the right side:

Join all like terms:

The general form of the quadratic equation is:

Solve the quadratic equation by using the formula:

In our equation: a=1, b=-2, c=-46
Substituting into the formula:



Since 188=4*47

Take the square root of 4:

Divide by 2:
