Question
y = (x - 1)(x + 2)(x + 2)
The graph in the xy-plane of the equation above contains the point (a, b). If -1
a1, which of the following is NOT a possible value of b ?
- -2
- -1
- 0
- 1
The correct answer is: 1
y = (x - 1) (x + 2) (x + 2)
The graph of the function is as follows
(a,b) satisfies the equation with 
In the interval the value of b is negative.
So, b cannot be 1.
Every term in a linear equation has an exponent of 1, so when it is graphed, it always results in a straight line. So, it is referred to as a "linear equation."
¶Both one-variable and two-variable linear equations exist. The linear equation formula is used to express a linear equation. There are numerous ways to accomplish this. For example, the linear equation can be expressed in standard, slope-intercept, or point-slope forms. Taking a linear equation in standard form,
¶Several methods for resolving linear equations in two variables include the graphical approach, substitution techniques, cross-multiplication techniques, elimination techniques, and determinant approaches.

The equation h = 150 + 10t gives the total number of housing units, h, in a community t months after a new zoning law was passed. How many housing units are added to the community each month after the zoning law was passed?
A graph illustrates the connection between two or more variables. An upward-sloping curve denotes a clear correlation between the two variables, and a curve with a downward slope denotes a negative correlation between the two variables.
A relationship between two variables can be measured and described using the statistical approach of correlation. Typically, the two variables are not changed. Therefore, two identical-person scores are necessary for the association. These results are represented as X and Y.

From 1990 to 2001, German currency included coins called pfennigs, worth 1 pfennig each, and groschen, worth 10 pfennigs each. Which equation represents the number of pfennig coins, p, and groschen coins, g, that have a combined value of 85 pfennigs?
Isolating a variable entails rearranging an algebraic equation so that one variable stands alone. A goal is to select a set of operations that will leave the variable of interest on one side of the equal sign while putting all other terms on the other.
¶To isolate a quantity in a formula or equation:
1. Make a note of the original equation. If necessary, convert the word problem or context into an equation.
2. Begin isolating the desired quantity by performing the operation on both sides of the equation.
3. Repeat Step 2 until you have isolated the desired quantity.
