Answer:
20² is 400
10² is 100
7² is 49
6² is 36
None of the options is correct but if you have to choose the closest answer then 6
A=(-1,-1) B=(1,3)C=(2,5)D=(-2,-3)E=(3,7)
The first graph is correct.
Although we cannot see the y-intercept, you can see a positive slope and that the y-intercept would be negative. The second graph has a negative slope, which would not work. And the 3rd graph has an intercept of -1, which is not correct.
(a) 9
(b) number of pens = 171/9 = 19
number of pencils = 63/9 = 7
number of erasers = 27/9 = 3
