-2x + 4 = y because the slope intercept form is mx+b=y
Distributive property of division: (a + b) : c = a : c + b : c
96 : 6 = (90 + 6) : 6 = 90 : 6 + 6 : 6 = (60 + 30) : 6 + 1
= 60 : 6 + 30 : 6 + 1 = 10 + 5 + 1 = 16
He would have to sale $500,000
9% of $500,000 is $45,000
So $30,000 plus $45,000 is $75,000
