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!
Hello live_laugh_luv27,
You know you have to find the slope of the line containing those two points, don't you?
$\displaystyle m=\frac{y_2=y_1}{x_2-x_1}$
Do that first. Next, use the point-slope form of the linear equation and do some substituting.
$\displaystyle y-y_1=m(x-x_1)$
You know what the slope (m) is from the formula above, right?
Use one of your points to substitute in for $\displaystyle x_1$ and $\displaystyle y_1$.
Move things around until you get it in your desired standard form:
$\displaystyle ax+by=c$ where c is a constant.
Good luck.
