quick graphs using slope intercept

  • Linear Equation is y = mx + b
  • "m" represents the slope. "b" represents the y-intercept.
  • . How to Graph Using y = mx + b Solve the equation for y. Determine the slope and y-intercept. Graph the y-intercept. Use the movements of slope (or rise/run) to graph more points begainning at the y-intercept. Connect the points with a straight line and arrows on each end. Label the line with its equation.

  • The "point-slope" form of the equation of a straight line is:
  • y - y1 = m(x - x1)
  • Using this formula, when we know: one point on the line and the slope of the line,
  • ...1 more annotation...
  • So this is the slope: and we can rearrange it like this:   to get this:

  • This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.
  • y = mx + b
  • y = mx + b (–6) = (4)(–1) + b –6 = –4 + b –2 = b
  • ...1 more annotation...
  • so far is a value for is b (which gives me the y-intercept). Then all I need to do is plug in what they gave me for the slope and the x and y from this particular point, and then solve for b

rate of change

  • The slope of a line tells us how something changes over time. If we find the slope we can find the rate of change over that period.
  • e was saving per month. This is called the rate of change per month.

  • We can't count the rise over the run like we did in the calculating slope lesson because our units on the x and y axis are not the same. In most real life problems, your units will not be the same on the x and y axis. So, we need another method!
