Question

What is the slope and y-intercept of the graph of 2x + 3y = 18?

Answer 1

mathhow.com or something like that. Google it, trust me.

Answer 2

try to isolate y
like bring it in the form y=mx+c

Answer 3

for that, first subtract 2x from both sides, what u get ?

Answer 4

3y=18-2x

Answer 5

@hartnn

Answer 6

yes, now to get y by itself, just divide 3 on both sides, what u get ?

Answer 7

y=6-2x

Answer 8

you for got to divide 3 to the term 2x
you should have got -2x/3 instead of just -2x

Answer 9

ohh ok but how do i divide 2x by 3

Answer 10

don't! keep it as it is ...
so, you have
y = -2/3 x +6
comparing with y=mx+c
you get slope = m = -2/3
and y-intercept = c = 6
got it ?

Answer 11

Yea
