Step-by-step explanation:
<u><em>Using Pythagorean Theorem:</em></u>
=> 
Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)
=> 
=> 
=>

, is a horizontal line, which makes it vertical to the y-axis
Technically nothing times 3 get you 16 but 3 times 5 equals 15 which is the closest answer but the answer would be 5.3
Answer:
y = -53/2, x = -17
Step-by-step explanation:
1/2x + 3/2 = -7
-3x +2y = -2
Isolate X for 1/2x + 3/2 = -7
X = -17
Substitute X = -17
-3(-17) + 2y = -2
Isolate Y for -3 (-17) + 2y = -2
Y = -53/2
