Question

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.

Answer 1

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
\[y-y_1=m(x-x_1)\]

Answer 2

What else do you want to know?

Answer 3

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

Answer 4

Give me a problem..

Answer 5

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?

Answer 6

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
\[y-1=2(x-2)\]

Answer 7

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

Answer 8

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

Answer 9

YES

Answer 10

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

Answer 11

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)

Answer 12

Its y-1=2(x-2)

Answer 13

Then option D is correct.
