To determine how to transform the first graph to make it become a non-proportional graph that has the same y-intercept as the second graph, we first need to analyze the two pricing structures:
-
The first business charges a flat rate of $22 per t-shirt. The equation can be represented as: \[ y = 22x \] where \( y \) is the total cost and \( x \) is the number of t-shirts.
-
The second business has a charge of $16 per t-shirt plus a $15 setup fee, which can be represented as: \[ y = 16x + 15 \]
The y-intercept of the first business (when \( x = 0 \)) is \( y = 0 \) because there is no fixed cost. The y-intercept of the second business is \( y = 15 \) when \( x = 0 \).
To make the first graph (which starts at (0, 0)) have the same y-intercept as the second graph (which is at (0, 15)), we need to transform it by moving it up 15 units.
So the answer is:
E. Up 15
