Determine if the relation y = 4x - 1 is a function by first graphing the relation, then applying the vertical line test. Enter 1 if the
relation is a function. Enter 2 if the relation is not a function. (1 point)
1
The graph of y = 4x - 1 is a straight line with a slope of 4 and y-intercept of -1. When graphed, this relation forms a straight line that passes through all points indicating that it passes the vertical line test and is therefore a function.
