How do you translate ordered pairs into an equation?

Answer 1

If you have a pair of coordinates you can find the slope then put it into either point slope or slope intercept form.

(2,3) and (5,4) has a slope of (3-2)/2-4) or 1/-2 or -1/2

Then you can put that in y-3=-1/2(x-2) as point slope

or y=-1/2(x) + b

3=-1/2(2) + b

4=b therefore y=-1/2x+4
