The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -6) and (2, 2) so the slope becomes:

A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.

The first step to solve a quadratic expression that's not set to zero is to solve the equation so that it is set to zero:

z² - 3z - 11 = -3z - 2
z² - 3z - 11 + 2 = -3z
z² - 3z + 3z - 9 = 0
z² - 9 = 0

Next, factor the quadratic equation:

z² - 9 = 0
(z - 3)(z + 3) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (z - 3) or (z + 3) must equal zero:

If (z - 3) = 0, z must equal 3
If (z + 3) = 0, z must equal -3

So the solution is that z = 3 or -3

A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.

An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
