Write the point-slope form of the line passing through (2, -12) and perpendicular to y = 3x. Oy-12--|(x+2)
Oy+12=- }(x-2)
O y + 12 = 3(x - 2)
Oy+12 = -3/X - 2)

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.
