y=5x-4 explane

The equation y = 5x - 4 represents a linear relationship between the variables y and x. This equation is in slope-intercept form, where the coefficient of x, 5, represents the slope of the line and the constant term, -4, represents the y-intercept of the line.

This means that for every unit increase in x, y will increase by 5 units. The y-intercept is the value of y when x is equal to 0, so in this case, the line intersects the y-axis at y = -4.

Overall, this equation describes a straight line in the Cartesian coordinate system with a slope of 5 and a y-intercept of -4.
