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




5x - 2 = 4
+2 +2
5x = 6
x = [tex]\frac{6}{5}[/tex] = 1 [tex]\frac{1}{5}[/tex]
Which graph shows the lines intersecting when x = 1 [tex]\frac{1}{5}[/tex]?
Answer: C
Answer:
Step-by-step explanation:
The given equation [tex]5x - 2 = 4[/tex] represents a vertical line because it doesn't have any y-variable. All vertical lines are expressed by the form [tex]x=k[/tex] where [tex]k[/tex] is a real number.
Basically, the right graph must show a vertical line that crosses the point
[tex]5x - 2 = 4\\5x=4+2\\5x=6\\x=\frac{6}{5}= 1.2[/tex]
As you can observe, there's no graph with vertical lines, so the right answer is "none of the above".
