Write the equation of the line that contains the specified points in the form ax+by=c, where a and b are integers.
1. (5,-5) and (2,4)
Thanks so much for any help!
You know you have to find the slope of the line containing those two points, don't you?
Do that first. Next, use the point-slope form of the linear equation and do some substituting.
You know what the slope (m) is from the formula above, right?
Use one of your points to substitute in for and .
Move things around until you get it in your desired standard form:
where c is a constant.
