Question

A line, often referred to as a line of best fit, that shows the general direction of points on a scatterplot.

a graph displaying values for two variables, graphed on a cartesian coordinate plan.

the number of times an event occurred in repeated trials of a chance process.

the ratio of the change in y to the change in x; the ratio of the rise to the run; also called the unit rate.

the equation of a line written as y=mx+b, where m is the slope and b is the y-intercept.

the point of a graph that intersects the y-axis.

the data of two variables.

a model that is nearly linear and is approximated by a trend line.

to predict by inferring unknown values from trends in known data.
