**Algebra**

Perpendicular slopes are negative reciprocals of each other (the product of one times the other is -1). In y=mx+b m is the slope and b is the y intercept. To find intercepts, just find (0,?) (?,0) Parallel lines have the same slope. Horizontal lines have a slope of zero, ...

3 (-2)^8 / 4 What is negative 2 times itself eight times? Should the sign be postive or negative with an even number for an exponent? Look at your rules for raising to a power, and then try again.
