Y-5 = 3x
a. m = 5, b = -3
b. m = -3, b = -5
c. m = -3, b = 5
d. m = -5, b = -3

What is the area of triangle abc if a = 8, b = 11, and c = 15?

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.
