Question

y=-7x-9

Answer 1

What about it?

Answer 2

Do you need to find the slope and y-intercept?

Answer 3

write an eqution of each line in standard form with integer coefficients

Answer 4

oh...hello newbie...welcome to openstudy

Answer 5

Standard form is
Ax + By = C

Answer 6

hi

Answer 7

ok

Answer 8

y = -7x - 9
add 7x to both sides
7x + y = -9 <-- standard form

Answer 9

how??

Answer 10

hello

Answer 11

y = -7x - 9
we want the -7x on the other side with the y term. So if we add 7x to both sides, because what you do on one side, you have to do on the other side....let me show you
y = -7x - 9 (add 7x to both sides)
y + 7x = -7x + 7x - 9 (combine like terms)
y + 7x = -9 (you see how the 7x terms on the right side cancel each other out)
Now rearrange the equation to standard for of Ax + By = C and you have 7x + y = -9

understand ?

Answer 12

thank u very much :)

Answer 13

no problem :)
