Given two points on a line, write an equation in point-slope form. But what's the slope? Oh, you have to figure out the slope first. That can be done given two points. Just use the rise over run slope formula. This isn't so hard after...

Given the coordinates for a point on a line and given the slope of that line, write an equation in point-slope form. Really, all that needs to be done is to use the formula for point-slope form and plug in the values.

There are many pieces and many parts to this problem. It seems simple enough to write an equation in slope-intercept form. In this problem, there is a given table of values and information from this table is used to get an equation...

Trying to write the equation for a horizontal line given an ordered pair? Just keep in mind that a horizontal line is all about the y value in the ordered pair. Plain and simple! Whatever the y value is in the ordered pair becomes the...

y=kx. This is the direct variation equation. You have been given a table of values. So look at the table and figure out how to use this equation to write an equation that represents what is happening in the table. Does the equation...
