## HOW DO I GRAPH Y=-2/5+5

# 3 Answers

I like the answers I saw on WyzAnt for this problem. Just one additional fine point that may be of use in other similar problems. A primary thing to note here is that there is no other variable in the equation except y ( x is unspecified and can be anything). Also observe that the value of y is specified as -2/5 + 5, which is 4.6. Therefore, the value of y is always 4.6 in this case, no matter what the value of x. So, in this two-dimensional case (plotting y versus x), the graph is a straight, horizontal line, crossing the y-axis at y = 4.6 .

y = -2/5 + 5 y = -2/5 + 25/5 y = 23/5 y = 4 3/5 y = 4.6

Graph: No matter what x is, y = 4.6. The graph is a line parallel to the x-axis, 4.6 units up on the y-axis.

It is very simple. The sum of -2/5 + 5 is 4.6. So, the graph is a horizontal straight line passing through y = 4.6
