Question

Which of the following has a graph that is a straight line?
1: y = 5x2 + 41

2: y = 14x5 − 4

3: y = 12x + 17

4: y4 = 2x − 1

Answer 1

Answer:

3: y=12x + 17 is the straight line equation

all others are parabolic equations

Answer 2

Answer:

y4=2x-1

Step-by-step explanation:

if either x or y has an exponent other than 1 the equation cannot be that of a straight
