Question

What is the equation in point-slope form of the line passing through (0, 2) and (1, 5)?

y − 5 = 3(x − 1)

y − 2 = −3(x − 0)

y + 2 = 3(x + 1)

y + 5 = −3(x + 1)

@amistre64 @ganeshie8 @iambatman Can anyone plz help me?

Answer 1

\[y-y _{1}=m(x-x _{1})\] point slope form, so first use the slope equation then plug in for (y_1,x_1)

slope (m) equation
\[ m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 2

(x_1,y_1) haha

Answer 3

but in the answer choices the it's written like this y − 5 = 3(x − 1) and the rest is similar but different numbers. the answer can't be (x1,y1) @iambatman

Answer 4

Yeah so fine the slope first and plug in (x_1,y_1)

Answer 5

ok

Answer 6

So you can plug in (0,2) for your x_1, y_1 but you still have to find slope m.

Answer 7

i got m= 3

Answer 8

You can do the same with other coordinates as well, so you have two answers

Answer 9

by point slope definition, we can narrow it to the other 2, and pick the 3 slope

Answer 10

yes A and C

Answer 11

Why c?

Answer 12

i meant the 2 answers that we know r right because of the slope.

Answer 13

@iambatman

Answer 14

what is it?
