Explanation:
Detailed explanation-1: -In the equation y = 4x-5, the constant term is-5. Thus, we have that the y-intercept of the graph of y = 4x-5 is (0, -5).
Detailed explanation-2: -The slope of y = 5x-4 is 5. Thus, it is in slope-intercept form. When the equation of a line is in slope-intercept form, we know that the slope of the line is equal to m, the coefficient of x. In y = 5x-4, the coefficient of x is 5. Thus, the slope of the line, y = 5x-4, is 5.
Detailed explanation-3: -Using the slope-intercept form, the y-intercept is −3-3 .
