Question

What is the slope of a line that passes through the point (−1, 1) and is parallel to a line that passes through (3, 6) and (1, −2)?

Answer 1

hint : the function of a line is f(x) = ax + b

Answer 2

It's not a function though, it's a slope.

Answer 3

Find the gradient of the points given?

Answer 4

It's trying to find the slope.

Answer 5

gradient is also called as the slope..so find the gradient of the two points given

Answer 6

I don't know how to do that, that's why I have it on here. It was on a test, and it was one of the questions I got wrong. So I just wanna know how to do it right.

Answer 7

6 = 3a + b
-2 = a + b

Answer 8

okay the gradient of a line, when two points are given can be found using the following equation


\[(x_{1}, y_{1}) and (x_{2},y_{2})\]

\[m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

Answer 9

find a and b... a is the slope

Answer 10

\[m = \frac{ -2 - 6 }{ 1-3 }\]
Is that right @thushananth01

Answer 11

yes :)

Answer 12

do I simplify?

Answer 13

you hve to :)

Answer 14

so then when I simplify, I got -4/-1, wouldn't that just be -4?

Answer 15

@thushananth01

Answer 16

No it's 4

Answer 17

- / - = +

Answer 18

ooooooh okay. Thanks :)
