Question

passes through (-1,1) slope -1

Answer 1

do you know the point-slope formula? :)

Answer 2

YES

Answer 3

thennn you would want to use that ! :)

Answer 4

OKA for this question it is point slope formula and what about this has y intercept 4 and x intercept -1

Answer 5

what formula for this one

Answer 6

yaas ^_^. Hmm.. the second one you would use the same thing.
But you should remember that y intercept at 4 means (0,4) and x intercept at -1 means (-1,0) :)

Answer 7

oh same formula for that one too you mean
y+=y1+m(x-x1)

Answer 8

we will plug in the value just?

Answer 9

and what about this one slope of 1/2 and y intercept -3

Answer 10

i think so..
You would want it in the form y= mx + b where "b" is your y intercept -3. :)

Answer 11

oka and passes through 5,-1 parallel to 2x+5y=15

Answer 12

you'd have to find the gradient of 2x+5y = 15 first. Then use that gradient and your point (5,-1) in the point slope formula again.

Answer 13

oh oka thank you so so much

Answer 14

no problem :)!

Answer 15

i need help with induction too

Answer 16

;(
