  • The lines intersect at zero points. (The lines are parallel.)
  • The lines intersect at exactly one point. (Most cases.)
  • The lines intersect at infinitely many points. (The two equations represent the same line.)
  • ...2 more annotations...
  • This method is useful when you just need a rough answer, or you're pretty sure the intersection happens at integer coordinates. Just graph the two lines, and see where they intersect!
  • Example: Solve the system by graphing. y = 0.5x + 2 y = –2x – 3

  • 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.

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.

  • ...1 more annotation...
  • 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!

  • The word slope (gradient, incline, pitch) is used to describe the
  • measurement of the steepness of a straight line.
