Question

What is the inverse of y=4x-2

Answer 1

y=4x-2

change:

x = 4y - 2
4y = x + 2
y = x/4 + 1/2 <--- inverse

Answer 2

`y=4x-2\\ \\reverse \ the \ x \ and \ y \ to \ get \\ \\ x=4y-2 \\ \\ solve \ for \ the \ new \ y \ to \ get \\ \\4y =x+2 \ \ / :4 \\ \\y=(x)/(4) + (2)/(4) \\ \\y=(1)/(4)x + (1)/(2)\\ \\ The \ answer \ is : \\ \\ y=(1)/(4)x + (1)/(2)`
