Question

what is the slope of the line that passes through the points (4,1) and (1,2)

Answer 1

Use the gradient formula to find out the gradient first.
Then use the gradient and one point and substitute it back into the general linear equation y= mx + c
where m is your gradient and c is your y-intercept.

Answer 2

okay now what?

Answer 3

what do u mean? what step are u up to?

Answer 4

im doing the equation that chelseachiodos told me

Answer 5

I will repost it if you'd like

Answer 6

@ChelseaChiodos, you can guide @blah500 then.

Answer 7

ok,
you have (x1,y1), (x2,y2)
answer is
Y-y1=m(X-x1)
where m=(y2-y1)/(x2-x1)

Answer 8

Alright.
You get the slope using the slope formula from the 2 equations provided like I said before.Then you take the slope that you got and plug it into the point-slope formula which is y-y1=m(x-x1).

Answer 9

okay

Answer 10

i'm sorry i explain line formula,
for slop you just compute
m=(y2-y1)/(x2-x1)

Answer 11

thats okay thanks though

Answer 12

do you want to help you?
