PLEASE HELP ANSWER THIS QUESTION I DON'T KNOW IT AT ALL
Lena [83]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

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]
