Foundation Practice

Match the following

• y=mx+b

• Standard Form

• Ax+By=C

• The coordinate where the function crosses the x-axis. At this point, y=0.

• SLOPE

• Measure of how STEEP a line is, can be found using rise/run

• y-intercept

• The coordinate where the function crosses the y-axis. At this point, x=0.

• x-intercept
