Question

I need to know how to do this please

Which equation is in standard form?
Answer
4x = y + 12
y = 3x - 18
8x + 10y = 21
3x + 9y + 9 = 4

Answer 1

the third one:8x + 10y = 21 because its of the form ax+by=c

Answer 2

ax + by = c is standard form?

Answer 3

and y = 3x - 18 is in slope intercept form y=mx+c

Answer 4

yes standard form of a st. line is ax+by+c=0, so the eq. 8x + 10y = 21 can be taken as 8x+10y-21=0

Answer 5

Ok! Thank you :)

Answer 6

i thought u had more questions, when you typed
