Final answer:
Jillian can represent the number of pumpkins she can buy with the equation 6m + 9l = 36. If she doesn't buy large pumpkins, she can buy 6 medium pumpkins. This is represented by the point (0, 6) on a graph, known as the intercept.
Step-by-step explanation:
To represent the number of medium and large pumpkins Jillian can buy, let m be the number of medium pumpkins and l be the number of large pumpkins. The cost of medium pumpkins is $6 each, and the cost of large pumpkins is $9 each. Jillian has $36 to spend, so the equation in standard form would be:
6m + 9l = 36
If Jillian does not buy any large pumpkins, then l is 0. The equation simplifies to 6m = 36, which means Jillian can buy 6 medium pumpkins, as m = 6.
On a graph, this scenario would be represented by a point on the horizontal axis (where l=0) at the coordinate (0, 6). This point represents the maximum number of medium pumpunks Jillian can afford without purchasing any large pumpkins and is often referred to as the intercept.
