correlation

Front

the relationship between paired data

Back

standard form of a linear equation

Front

Ax + By = C, where A, B, and C are real numbers and A and B are not both zero

Back

equivalent equations

Front

equations that have the same solution(s)

Back

best fitting line

Front

the line that most closely follows a trend in data, found using technology

Back

point-slope form

Front

an equation of a non-vertical line written in the form y - y1 = m (x - x1) where the line passes through a point of (x1, y1) and has a slope of m

Back

scatter plot

Front

a graph used to determine whether there is a relationship or trend between paired data

Back

zero of a function

Front

an x-value for which f(x) = 0 (or y = 0)

Back

converse

Front

a statement formed by interchanging the hypothesis and the conclusion of the conditional

Back

interpolation

Front

using a line or its equation to approximate a value between two known values

Back

extrapolation

Front

using a line or its equation to approximate a value outside the range of known values

Back

conditional statement

Front

a statement with a hypothesis and a conclusion

Back

slope

Front

a non-vertical line is the ratio of vertical change (the rise) to horizontal change (the run) between any two points on a line

Back

perpendicular lines

Front

two lines in the same plane that intersect to form four right angles

Back

slope-intercept form

Front

a linear equation written in the form y=mx+b where m is the slope and b is the y-intercept of the equation's graph

Back

y-intercept

Front

the y-coordinate of a point where a graph crosses the y-axis

Back

line of fit

Front

a line used to model the trend in data having a positive or negative correlation

Back

negative reciprocals

Front

the fraction flipped with the opposite sign

Back

linear regression

Front

the process of finding the best fitting line to model a set of data

Back

parallel lines

Front

two lines in the same plane that do not intersect
