now you have the slope so once again plug in the points to y=mx+b.

you get y=-4x+14

hope i helped you

your formula you would use on your 2nd question you have just asked is y=mx+b. m equaling the slope an b equaling the y intercept. they already gave you the slope which is -4 so, so far you have y=mx+2. Now plug in the slope in M. you will get y=-4x+2 that is your answer

next problem

y=mx+b Ax+By=C

plug in what you need

2=-4(3)+b

2=-12+b

14=b so… y=-4x+14

standard from take -4x to other side you get

4x+y=14

I just learned this, so give me a second to work it out..

Oh god, I’m sorry for spamming because I thought I knew =(
