Answer:
b.) 2
Explanation:
Parallel slopes have same slope.
Perpendicular slopes have negatively inverse slope.

Comparing it with slope intercept form, "y = mx + b" where m is slope.
Here parallel slope: -1/2
Perpendicular slope: -(-1/2)⁻¹ = 2
Answer:
(7, 46)
Step-by-step explanation:
The offered answer choices have x-values of 7, 9, 10. The corresponding upper limit of y-value is ...
x=7 : y < 8·7 -3 = 53 . . . . . 46 is in the solution set, 60 is not
x=9 : y < 8·9 -3 = 69 . . . . 82 is not in the solution set
x=10 : y < 8·10 -3 = 77 . . . . 89 is not in the solution set
Of the choices offered, only (7, 46) is in the solution set.
The other two angles would also be 120 and 40 because the opposite angles of parallelograms are equal
