Question

Which graph represents the solution for the equation 5x - 2 = 4?

Answer 1

5x - 2 = 4

    +2    +2  

5x      = 6

 x = $\frac{6}{5}$ = 1 $\frac{1}{5}$

Which graph shows the lines intersecting when x = 1 $\frac{1}{5}$?

Answer: C

Answer 2

Answer:

None of the above

Step-by-step explanation:

The given equation $5x - 2 = 4$ represents a vertical line because it doesn't have any y-variable. All vertical lines are expressed by the form $x=k$ where $k$ is a real number.

Basically, the right graph must show a vertical line that crosses the point

$5x - 2 = 4\\5x=4+2\\5x=6\\x=\frac{6}{5}= 1.2$

As you can observe, there's no graph with vertical lines, so the right answer is "none of the above".
