Question

Which of the following best describes the equation below? y = 5x - 15

a.neither linear or non linear
b.non linear
c.both linear and non linear
d.linear

Answer 1

D linear

Explanation:

We can tell pretty easily that this is a linear equation. How? Look at the highest degree of x!

This means the highest exponent of x. It looks like we have 5x, which you can think of as 5x to the first power. Whenever the highest exponent is 1, the equation is linear.

Answer 2

The answer is d because 3x5=15
