Find the equation of the ine that contains the point (5, - 1) and has slope 1/5.

Question

please help!

Answer 1

We know that

y = mx + c

where m is the slope, so the equation we're looking for has to be

y = (1/5)x + c

(or y = x/5 + c, which is easier to write n this board!)

Now all we have to do is find c.

We know that (5, -1) must satisfy the equation, do to find c:

y = x/5 + c

-1 = 5/5 + c

and I'll leave you to finish it from there.
