I answered the two questions below and the two graphs:)
Step-by-step explanation:
7y−5x=14
Step 1: Add -7y to both sides.
−5x+7y+−7y=14+−7y
−5x=−7y+14
Step 2: Divide both sides by -5.
−5x
−5
=
−7y+14

x=

y+
−14
5
y=−2x−1
Step 1: Flip the equation.
−2x−1=y
Step 2: Add 1 to both sides.
−2x−1+1=y+1
−2x=y+1
Step 3: Divide both sides by -2.
−2x
−2
=
y+1
