Question

Select all of the equations that represent linear relationships.

Answer 1

There are linear relationships so long as the power of x is 1 when power of y is 1 / power of x is not 2 and above when power of y is 1. This is assuming you plot the vertical axis as y-axis and the horizontal axis as the x-axis.

So using this concept, the equation with linear relationships are:
1, 3, 4, and 5.

Hope this helps! :)

Answer 2

1). 5 + 2y = 13  3). y – 5 = 2(x – 1) 4). y/2 = x + 7 5).x = –4
Are all correct
