The slope of the line represented by the equation y = 5x is 5.
In this equation, the format is a linear equation in slope-intercept form, which is typically written as y = mx + b, where m represents the slope and b represents the y-intercept.
In our case, the equation has no constant term added (the b), so it can be seen as y = 5x + 0. This clearly indicates that the slope (m) is 5 and the y-intercept is at the origin (0,0).
A slope of 5 means that for every unit increase in x, the value of y increases by 5 units. This also indicates that the line rises steeply as it moves from left to right on the graph.
