-1 is the y-intercept of the equation.
Because he divided his cake into 6 equal pieces, we can represent the eaten and remaining amounts with fractions.
Remember that a fraction is the ratio of number of pieces over the total pieces.
So, we need to figure out how much cake needs to be subtracted.
We know his sister ate 1/6 of the cake and he ate 3/6 of the cake. We can add these fractions together because they have common denominators.
3/6+1/6=4/6
So, we need to subtract 4/6 from the whole:
6/6-4/6=2/6, so 2 slices out of the 6 remain.
He only multiplied 6 by 5, and forgot the r to get 30+r=96. The correct solution is 30 + 6r = 96, or 6r=66. Divide both sides by 6 to get r = 11.
