Use exact numbers.

Answer 2

solve in y=mx + b format

Answer 6

Well first we have to plug in the points so how can we do that for a y=mx+b equation?

Answer 7

-2

Answer 8

is the slope right

Answer 9

Well for the points it would be (x,y) so with that how would you plug the numbers in?

Answer 10

ima use 4 and 1

Answer 11

Alright so how would that look in the equation?

Answer 12

y - 4 (-2) x - 1

Answer 13

is that right

Answer 14

slope formula

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

pick one of your points to be x1,y1, and the other one to be x2,y2. plug in to get the slope.

once you have the slope, you can plug in the slope into the point-slope form y - y1 = m(x-x1), once again, plugging in either point to be your x1,y1, then solve for y.

Answer 15

no

Answer 16

u do 2 -1

Answer 17

lmao thats what i meant

Answer 18

-2/1 is the slope

Answer 19

my bad let me rewrite tht

Answer 20

okay there we go

Answer 21

I need to find y also

Answer 22

answer has to be in y = mx + b format

Answer 23

wouldnt it be y=-2x+1?
