Question

PLEASE HELP ANSWER THIS QUESTION I DON'T KNOW IT AT ALL

Answer 1

PLEASE MARK BRAINLIEST!

Answer:

1. Is y = 4x - 7 a linear function?
2. Is y = 6x² - 1 a linear function?
3. Is y = $\frac{1}{2x}$ + 10 a linear function?

Step-by-step explanation:

1. Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
2. No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
3. No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.

For the graphs -

• The first one represents the linear function [y = 4x - 7]

• The second one (that looks like an L) represents the last not linear function [y = $\frac{1}{2x}$ + 10]

• The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]

I HOPE THIS HELPS!
