1. a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
2. An equation defined as Ax + By = C, where A, B, and C are real numbers, and A and B are both not zero
3. ___________ is a sentence of the form ax+by+c<0, ax+by+c<0, where a and b are not both zero; c can be any real number.
4. a line through a scatter plot of data points that best expresses the relationship between those points.
5. refering to two numbers that have opposite signs and are flipped fractions of each other.
6. two lines that are always the same distance apart and never touch.
7. the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line
8. divides the coordinate plane into two halves by a boundary line (the line that corresponds to the function). One side of the boundary line contains all solutions to the inequality. The boundary line is dashed for > and < and solid for ≥ and ≤.
9. two lines intersecting at a right angle and having opposite reciprocal slopes.
