Q:

(70 points)Which of the following has a graph that is a straight line? Equation 1: y = 5x2 + 41 Equation 2: y = 14x5 βˆ’ 4 Equation 3: y = 12x + 17 Equation 4: y4 = 2x βˆ’ 1Which of the following ordered pairs could be placed in the table and still have the relation qualify as a linear function? Input(x) Output(y)1 123 95 6? ? (7, 3) (7, 10) (3, 3) (3, 10)

Accepted Solution

A:
It's important that you use the " ^ " symbol to denote exponentiation:

Equation 1: y = 5x^2 + 41
Equation 2: y = 14x^5 βˆ’ 4
Equation 3: y = 12x + 17
Equation 4: y^4 = 2x βˆ’ 1

If either x or y has an exponent other than 1, the equation cannot be that of a straight line.

Please, could y ou post your other question separately, and make a neater table of your data? Β Thanks.
