28/2 or 28 x (1/2)
You can either divide $28 by 2 or multiply it by (1/2)
Answer: −8x−9
Step By Step:
Distribute the Negative Sign:
=−7x−14+−1(x−5)
=−7x+−14+−1x+(−1)(−5)
=−7x+−14+−x+5
Combine Like Terms:
=−7x+−14+−x+5
=(−7x+−x)+(−14+5)
=−8x+−9
Answer:
= −8x−9

Answer:
C
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 1) ← 2 points on the line
m =
= - 
y = -
x ← equation of line
