A purple exponential curve and a green line on a coordinate plane with horizontal x-axis ranging from negative 10 to 10 in increment of 5 and the vertical y-axis ranges from negative 10 to 10 in increments of 5. The exponential curve begins in the second quadrant. The curve decreases through begin ordered pair 0 comma 1 end ordered pair. The curve passes through begin ordered pair 1 comma 0.5 end ordered pair and exits the first quadrant. The line begins in second quadrant and decreases through begin ordered pair 0 comma 0 end ordered pair. The line passes through begin ordered pair 1 comma negative 2 end ordered pair and exits the fourth quadrant. The curve and line intersect at begin ordered pair negative 1 comma 2 end ordered pair and begin ordered pair negative 2 comma 4 end ordered pair.
