Linear Functions
Question | Answer |
---|---|
what is slope- intercept form? | y=mx+b |
In what form are constant increase or constant decrease situations in? | slope-intercept form |
when are two lines parallel? | If they have the same slope |
when does a line have no slope? | If it is vertical. |
What is a linear combination? | When all variables are to the first power and are not multiplied by each other. |
Standard form of an equation for a line | Ax+By=C |
Point-Slope Theorem | If a line contains (x*1, y*1), then it has equation y - y*1 = m(x - x*1) |
arithmetic sequence | A sequence with a constant difference |
nth Term of an Arithmetic Sequence | The nth term of a*n of an arithmetic sequence with first term a*1 and constant difference d is given by the explicit formula a*n = a*1 + (n - 1)d. |
