## Shelebrate 3 years ago Ok, I need help on how to graph with Point Slope form. Like how to get something to Point slope form and then how to graph it.

1. 2bornot2b

Suppose you are provided with a point, e.g. \((x_1,y_1)\), and a slope \(m\) so the line passing through that point and having that slope is \[y-y_1=m(x-x_1)\]

2. 2bornot2b

What else do you want to know?

3. Shelebrate

Yes I know that but what about how to solve it and graph it

4. 2bornot2b

Give me a problem..

5. Shelebrate

I'm not sure how, but I have this one I don't understand. Wrate an equation of the line that passes through (2,1) and is Parallel to the line Y=2x+7 A. y-2=2(x+1) B. y-1=1/2(x-2) C. y+1=1/2(x+2) D. y-1=2(x-1) How do I solve this?

6. 2bornot2b

So your line passes through the point (2,1) and it is parallel to the line y=2x+7 which means your line should have a slope of 2 (when a line is expressed as y=mx+c, m is the slope of the line, here y=2x+7 therefore has a slope of 2, and since you want to find a line parallel to it, your line will also have a slope 2) So now the equation of your line would be \[y-1=2(x-2)\]

7. Shelebrate

Oh! Ok I kinda get it, but is the last 2 the 2 from the (2,1)

8. 2bornot2b

You typed the option D wrong. It should be D. y-1=2(x-2)

9. 2bornot2b

YES

10. Shelebrate

Ok! Thanks that makes so much sense to me now. But which letter would it be?

11. 2bornot2b

It should be D, though you typed it wrong here. Check it, I think it should be y-1=2(x-2) instead of y-1=2(x-1)

12. Shelebrate

Its y-1=2(x-2)

13. 2bornot2b

Then option D is correct.
