Type the slope-intercept equation
Zolol [24]

Answer: y=x-2

Step-by-step explanation:

P=(x1,y1), and Q=(x2,y2), we use this to find m because m=y2-y1/x2-x1, by using this you'll see that the slope equals one. So now we have our slope. To solve for b, you need to do b=y1-m*x1, or b=y2-m^x2, it doesn't matter which one you do because the results will be the same, but it is good to check over it. Now that you have your slope and y-intercept, you can put it into the equation y=mx+b, so the answer to the problem is y=x-2.

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
