What's that term?
This measures the distance between x and 0 on the number line, and is denoted |x|.
What is absolute value of x?
A line has this feature, which can be defined as rise over run.
What is slope?
This is the number of solutions to a system of linear equations with parallel lines.
What is zero?
This kind of inequality is really two inequalities separated by the word "or" or "and".
What is a compound inequality?
This is the property of two lines with slopes m and -1/m.
What are perpendicular lines?
This is the number of solutions to a system of linear equations that has coincident lines.
What is infinitely many?
In a right triangle, this major result says that the side lengths satisfy a2 + b2 = c2.
What is the Pythagorean Theorem?
This form of a line is written y = mx + b
What is slope-intercept form?
What is a solution to a system of linear equations (in three variables)?
This is a list of ordered pairs (x,y), where each x-value corresponds to exactly one y-value
What is a function?
This form of a line is written y - y1 = m(x - x1)
What is point-slope form of a line?
This strategy is most useful for solving systems such as
3x + 4y = 7
y = x+1
What is the substitution method?
This test helps you determine whether a graph is a function - A function should only intersect one of these shapes just once!
What is the Vertical Line Test?
This kind of line is written as y = b
What is a horizontal line?
This method is most helpful for solving
x+ 2y = 10
3x -2y = 2
What is the elimination method?
