5. Elena wanted to find the slope and y-intercept of the graph of 25% - 20y = 100.She decided to put the equation in slope-intercept forrn first. Here is her work-25x – 20y = 10020y = 100 – 25x5y = 5 - -y=5.5- 5. Describe Elena's mistake in her work above, and what the correct slopeand y-intercept of the line are.What are the x- and y-intercepts of the equation 4y + 9x = 18?
