    This page is a resource for Doctor Wheeler's students in composition and literature. The page contains a list of logical fallacies from the Western European tradition of philosophy, and the intended audience is writing students taking freshman composition classes. The page is still under construction and I will be adding to this website over the term.

  • 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 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.

  • 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!

  • Use properties of equality together to isolate variables and solve algebraic equations.
  • Subtract 2 from both sides of the equation to get the term with the variable by itself.
  • Problem Solve 3y + 2 = 11.
  • ...3 more annotations...
  • Use the properties of equality and the distributive property to solve equations containing parentheses, fractions, and/or decimals.
  • Divide both sides of the equation by 3 to get a coefficient of 1 for the variable.
  • Answer y = 3

  • The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected. How many children and how many adults attended?
  • Many problems lend themselves to being solved with systems of linear equations. In "real life", these problems can be incredibly complex. This is one reason why linear algebra (the study of linear systems and related concepts) is its own branch of mathematics. In your studies, however, you should generally be faced with much simpler problems. What follows are some typical examples.
  • Now I can solve the system for the number of adults and the number of children. I will solve the first equation for one of the variables, and then substitute the result into the other equation:

  • This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.

  • 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
