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

PLEASE MARK BRAINLIEST!Answer:Is y = 4x - 7 a linear function?Is y = 6x² - 1 a linear function?Is y = [tex]\frac{1}{2x}[/tex] + 10 a linear function?Step-by-step explanation:Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function. 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.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 = [tex]\frac{1}{2x}[/tex] + 10]The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]I HOPE THIS HELPS!
