Vocaloid:

@zarkam21 not D, check your signs again

zarkam21:

A?

Vocaloid:

first let me know what you got for the y = mx + b form

zarkam21:

slope is -2/7

Vocaloid:

good, you should get y = 17/7 - 2x/7 as your y = mx + b form now re-arrange that to standard form and watch your signs carefully

zarkam21:

y=-2/7x+17/7

Vocaloid:

now re-write that so the x and y terms are on the same side.

zarkam21:

\[\frac{ 2x }{ 7 }+y=\frac{ 17 }{ 7 }\]

Vocaloid:

great job! now multiply everything by 7

zarkam21:

ohhh B?

Vocaloid:

yup good
