Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.

Answer:
D. -6
Step-by-step explanation:
SInce x is negative, the - before the six would be cancelled out leaving the equation to be 6^3=216 which is correct
Answer:
1/8
Step-by-step explanation:
To make any decimal into a fraction, it will need to be over 1. 0.125 needs to be put over 1.
= 0.125 / 1

= 1 / 8
Answer:
7(x-2)(x+2)
Step-by-step explanation:
7x^2 -28
Factor out a 7
7(x^2 -4)
The terms inside the parentheses is the difference of squares, so it is factorable (a^2-b^2) = (a-b)(a+b)
7(x-2)(x+2)
