Question

through: (2,1) , Slope= 2

Answer 1

Find an equation of a line?

Answer 2

yes , Im Having Trouble On Theese Type of Problems @iPwnBunnies

Answer 3

Ok, use the point-slope equation to build an equation for a line.
\[y - y1 = m(x-x1)\]
Where (x1,y1) is the given point and 'm' is the slope.

Answer 4

so how do I set the problem up

Answer 5

Plug in the numbers, then expand it, then solve for y.
\[y - 1 = 2(x-2)\]

Answer 6

so y=2x-3

Answer 7

Yes. :)

Answer 8

thats all i have to do for theese types of problems

Answer 9

Ok, well, you got it.

Answer 10

Thanks So Much , One More Question If I have A Problem With No Slope Then How Do I Set It Up Same Way ... Ex: Through (0,2) and (-4,1)

Answer 11

You'll have to find the slope of the line formed between the two points, using slope formula.
Then, choose a point, and use the point-slope equation again.

Answer 12

\[slope = \frac{Y2 - Y1}{X2 -X1}\]
Where (X1,Y1) is one point and (X2,Y2) is the other point.
