Determine if the relation y = 4x - 1 is a function by first graphing the relation, then applying the vertical line testEnter 1 if the relation is a functionEnter 2 if the relation is not a function point)

Answer 1

To determine if the relation y = 4x - 1 is a function, we first need to graph the equation.

The graph of the equation y = 4x - 1 is a straight line with a slope of 4 and a y-intercept of -1.

Next, we apply the vertical line test. If a vertical line passes through the graph only once at every point, then the relation is a function.

In this case, the relation passes the vertical line test, as every vertical line intersects the graph at only one point.

Therefore, the relation y = 4x - 1 is a function.

Enter 1.
