Answer:
line c
Step-by-step explanation:
The graph representing a direct variation equation always passes through the origin. This could be graphs (a) or (c)
given y = 
x
with slope =
Since graph (a) slopes down from left to right it's slope is negative
Hence it is not graph (a) as the slope given in the equation is positive.
Hence the required graph is (c)
The vertical angles are equal to each other, that is, one of the one-sided corners will be 116°.
The sum of the one-sided angles is 180°, which means: 4x+116 = 180°
4x = 180-116 => 4x = 64°
x = 64/4 = 16°.
The sum of two adjacent angles is 180°. which means, that: 2x-3y = 180-64 = 116°
2x-3y = 116°
-2x+3y = -116
-32+3y = -116
3y = -116-(-32)
3y = -84
y = -84/3 => y = -28.
