Find the equation of the tangent line to 9x^2+16y^2=52 through (2,-1). a. -9x+8y-26=0. b. 9x-8y-26=0. c. 9x-8y-106=0. d. 8x+9y-17=0. e. 9x+16y-2=0 . the slope is 9/8 idk where to go from

1- 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. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
