help me pls

[steep tusk]

I have to find the distance of the point from the straight [cartesian plane]

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

i have tried to resolve these both but none of the results comes the same as the one besides in grey

If we have a point (x0, y0) and a line ax + by + c = 0, then the distance between them is:
d = |ax0 + by0 + c|/√(a^2 + b^2)

[steep tusk]

i have tried it

it doesn’t come out the same

[bronze karma]

What did you get?

[steep tusk]

this is the second i tried

[grave heath]

hard to discern with your handwriting

[steep tusk]

i can rewrite better

[grave heath]

can you write clearly so that we don't misinterpret 😅

[steep tusk]

[bronze karma]

You substituted x0 and y0 instead of a and b into the denominator.

[grave heath]

lmal

[steep tusk]

lol

which one is supposed to be a and b?

[grave heath]

bruh.

[bronze karma]

Coefficients of x and y in the expression of the line, of course.

I've written the formula above.

[steep tusk]

so x is the a

and y the b?

[steep tusk]

the ones stated in the line

[bronze karma]

No. As I said:
If we have a point (x0, y0) and a line ax + by + c = 0, then the distance between them is:
d = |ax0 + by0 + c|/√(a^2 + b^2)

You, however, wrote d = |ax0 + by0 + c|/√(x0^2 + y0^2).

[steep tusk]

yes

i solved it

that was the most stupid mistake you’ve probably seen in this server

sorry for wasting time and thanks in advance

😹
