An Introduction to Linear Functions

For the most part, students did a terrific job on their concept 6 test. Most were very pleased with their results, and so was (! (Who wouldn't be when the average score was 88%????)

Students were introduced to the standard form of a linear equation. There are two forms that are generally accepted:

Ax + By = C and Ax + By + C = 0

Either form is acceptable to use in my class, although I find the first one more usable when determining x and y intercepts.

We then talked about needing just two points to draw a straight line. Given that this is true, it may be easiest to use the standard form of a linear equation to determine the x and y intercepts. To do this, just substitute zero in for the value of one of the variables, and solve for the other.
