Question

Write the equation y - 2 = 4(x + 5) in standard form

Answer 1

distribute and then move terms all to the right leaving it as y=mx+b

Answer 2

*Ax+By=C

Answer 3

That's slope-intercept form.. I think standard form is AX+By=C

Answer 4

Oh is it... haha, i see. ok.

Answer 5

Aw, why'd you delete your work?

Answer 6

Because it's the wrong explanation lol. I just woke up -_-

Answer 7

Haha, doesn't mean it wasn't helpful.
So yea @MakeMeSmile332 just do that and let's see what you get :)

Answer 8

4x - y = -22?

Answer 9

What are you typing Jhann, a novel? :P
and correct

Answer 10

Standard form \[\large \color{green}Ax+\color{blue}By=C\]you have your y's and x's on both sides of the equation, so you want to put them all on one side, and put all your numbers on the other. \[\large \color{blue}y-2=4(\color{green}x+5)\]start by distributing the 4 to (x+5)\[\large \color{blue}y-2=4(\color{green}x)+4(5)\]now subtract your 4(x) so it can be on the left side. \[\large \color{blue}y-2-4(\color{green}x)=-4(\color{green}{x})+4(\color{green}{x})+4(5)\] add +2 to both sides to get rid of the 2 on the left side. \[\large \color{blue}y-2+2-4(\color{green}x)=4(5)+2\]simplify \[\large \color{blue}y-4(\color{green}x)=4(5)+2\]

Answer 11

haha. good job

Answer 12

It'll be +22, :P not -22!

Answer 13

We got -22

Answer 14

really? O_o

Answer 15

\[y-2=4(x+5)\]
\[y-2=4x+20\]
\[-4x+y=22\]
multiply a negative since Ax cannot be negative
\[4x-y=-22\]

Answer 16

Oh, I just looked it up! you CAN have a negative Ax, but it's just proper to multiply a negative across to fit the standard form of the equation better

Answer 17

Ha, well then.
@MakeMeSmile332 nice job, you didn't need us at all :P

Answer 18

xD goood job!
