If (3, y) lies on the graph of y = -(2x), then y =?

Solution:

Given y = -2x and the point (3, y) lies on the graph

We know that if a point lies on the graph, it must satisfy the equation

Each point is defined by a pair of numbers containing two coordinates. A coordinate is one of a set of numbers used to identify the location of a point on a graph.

Each point is identified by both an x and a y coordinate.

So, put x = 3 and y = y in given equation

y = -(2(3))

y = -(6)

y = -6

Hence, the value of y is -6.

If (3, y) lies on the graph of y = -(2x), then y =?

Summary:

If (3, y) lies on the graph of y = -(2x), then y = -6.
