• m=y2-y1

  -----------

  x2-x1

• y=mx+b

• rise

  -------

  run

What is the slope?

hint: use the formula y2-y1 over x2-x1

• 2

• -1/3

• 3

• 1/2

What is the y-intercept?

hint: x has to equal zero so....

• undefined

• zero

• -2

• 3

what are other terms for y-intercept?

• where you 'begin' your graphing

• the 'base' amount

• where a line crosses the y-intercept on a graph

• the rate of change
