Which graph would illustrate that a change to clean, sustainable energy has decreased the need for fossil fuels, thus increasing production by decreasing costs? Group of answer choices A line graph. The y-axis is labeled Price Level and has two points, P and P1, which is located below P. The x-axis is labeled Real GDP and has two points, Y and Y1, which is located to the left of Y. Line AD slopes down and to the right. A point on the AD curve has a dotted line which extends to the y-axis where it is marked P and down to the x-axis where it is marked Y. Line AD1 slopes down and to the right, parallel, and to the left of line AD. A point on the AD1 curve has a dotted line which extends to the y-axis where it is marked P1 and down to the x-axis where it is marked Y1. There is an arrow between lines AD and AD1 pointing to the left from line AD to line AD1. Line AS is curved up and to the right and intersects the points on lines AD1 and AD. An aggregate supply and demand graph. The x axisWhich
