The explanation for graphing and interpreting key features of lines is:
Graphing and interpreting key features of lines involves analyzing the slope and intercept of the line.
Why do we graph lines?
A line graph connects individual data points that, typically, display quantitative values over a specified time interval.
Graphing and interpreting key features of lines involves analyzing the slope and intercept of the line. The slope of a line describes its direction and steepness, and is equal to the ratio of the change in outputs to the change in inputs.
The intercept of a line is the point where it crosses the y-axis, and is indicated by the value of the y-coordinate when x=0. To graph a line, we can plot points and then draw a line through them, or use the slope and intercept to determine additional points.
Line graphs are often used to visualize changes in values over time, and can be used to compare different variables
