3.1 Write a script that creates two subplots in a two-column, one-row window. The first subplot draws hl and h2, where hl is x + y =1, using ezplot function and h2 is x? /16+ y2/4=1, using ezplot function. Let x and y be from -5 to 5. Turn both grids on. Set hl as red and h2 as green. Remember to set axis equal, legend and place title as 'First Figure. The second subplot draws two functions yl and y2, where yl=x and y2 = x using plot function. Let x be from -10 to 10 with increment 0.1. Remember to set legend, title as Second Figure, x-axis label as xand y-axis label as y.' Use yl in blue color, dotted line and y2 in red color, solid line. Turn grids on. Note that you should plot both according to the above instruction. Show the script file and resulting figure
