Last question was wrong. Line l and line m are straight lines. What is the measure of angle y?

y+43°= 180°( straight angle)

=>y= 180°-43°

=>y=137°

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
