Hi!
So for this problem, we're given the y-coordinate and we can plug that in for y in the equation. So let's do that
-1 = -3/5x - 7
6 = -3/5x
30 = -3x
-10 = x
The missing coordinate would be x, assuming that the equation was y = (-3/5)x - 7
I Can't Figure That Out, Because X Is Unknown. So I Still Don't Know If He Used 900 Grams Of Flower, How Many Eggs He Used. The Answer Is X, Since We Don't Know How Much X Is.
