Final answer:
All equations are already in the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. The slopes and y-intercepts of the equations are explained.
Step-by-step explanation:
The given equations are already in the slope-intercept form which is defined as y = mx + b. In this equation, 'm' represents the slope, and 'b' is the y-intercept. For instance, equation A) y = -15x + 9 has a slope of -15 and a y-intercept of 9. Similarly, equation B) y = -5x + 3 has a slope of -5 and a y-intercept of 3. Equation C) y = 5x - 15 has a slope of 5 and a y-intercept of -15, and equation D) y = 15x - 9 has a slope of 15 and a y-intercept of -9.
