Question

how do I Change 2x + 5y = –30 to slope-intercept form and State the slope and y-intercept??? someone plz help! I need somebody's help!

Answer 1

You have to find y in terms of x for that..

Answer 2

Firstly subtract 2x from both the sides and tell me what you get??

Answer 3

2x + 5y = –30
5y = -2x - 30
y = (-2/5)x-6

Answer 4

Yes you are right..

Answer 5

Now compare your answer with the following equation:

\(y = mx + c\)

Tell me what is m there in your solution??

Answer 6

Or simply tell me what is the coefficient of x there in your answer??

Answer 7

5y = -2x +30

Answer 8

@Nana3456 your first equation is right..


See, it is an example I am giving to you:

See,

if y = -6x + 3

Then here coefficient of x is -6

Similarly you have the equation:

\[y = -\frac{2}{5}x - 6\]

Tell me what is the coefficient of x here??

Answer 9

:( I dont know ,,I always have problems with this kind of exercirses

Answer 10

So Slope = \(\frac{-2}{5}\) and y - intercept = \(-6\)..

Answer 11

ok :)

Answer 12

Okay..

Answer 13

so that it?? :? :)

Answer 14

And how do I state tthwe sloppe ans y intercept?

Answer 15

Read the question carefully,,

Simply state it as:

Slope = \(\frac{-2}{5}\) and y - intercept = -6

Answer 16

ok so I just leave it like that

Answer 17

That is the answer you can't do more in that..

Answer 18

ok thank oyou again:))

Answer 19

Welcome dear.
