Answer:
Jenny marks 414 different points on the coordinate plane.
Step-by-step explanation:
A point on a coordinate plane is represented by (x, y)
The possible values of x include all the integers between -12 and 7; that is,
-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6.
The possible values of y include all the integers between -12 and 12; that is,
-11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.
This means that each x-value can take on each y-value.
There are 18 x-values and 23 y-values.
Each x-value can form 23 different coordinates with all the available y-values.
18 x-values will form 18 × 23 different coordinates with the all the available y-values.
The total number of points that Jenny marks = 18 × 23 = 414.
Hope this Helps!!!
