Hello. I dont know how to change this formula to find the original one (y = mx+b).
I have to find the slope and the y-intercept.
I do not want you to give the answer, I need help to be able to do that on my own.
I also have to trace the line after... that should be ok!
Solve: `-6y - x - 18 = 0` for y.
In order to solve for y we most move everything to the right of the equal sign. We do this by "undoing" the operation.
First, add 18 to both sides. When we do this, (-18 + 18) on left will make 0. This gives:
`-6y - x = 18` Next we will add x to both sides to "undo" the minus x. Just like the 18 on previous step. This gives:
`-6y = x + 18` Finally, we will divide all terms by -6, as -6/-6 will make just 1y. This gives:
`(-6y)/-6 = x/-6 + 18/(-6)`
``Simplify everything to give:
`y = -1/6x - 3`
Now that it is written as y = mx + b we can identify slope and y-intercept.
m - slope = `-1/6`
b - y-intercept = `-3`
since it is telling you to solve for y you move all the other numbers to the right by adding the opposite for example: the opposite of -9 would be +9 and the opposite of x would be -x
to get y by itself you need to divide by -6 as it is the number in front of x
`(-6y)/(-6) = x/(-6) + (18)/(-6)`
so the slope will be -1/6 and the y intercerpt= -3
This time, I have to put the correct y = mx+b form into the asnwer box, check if the numbers are part of a Linear (or input N if not).
there are ALWAYS those 2 that im wrong. I tried 10 time.
because b is 0 or 0.00, it gives me wrong.
also, itsnt like f(g) or f(x) its a capital Letter. I expect the formula will be different...
Im clueless. i dont know what to do. thank you!
oh great! thank you!
It looks so simple when we have the answer...
