Answer:
i didn't learn algebra or geometry or spatial sense when i was in sixth grade
Step-by-step explanation:
- Parallel lines have the same slope but different y intercepts.
- turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
- divide the equation by -1 in order to make y positive and you get y=x-7
- So rewrite the equation with the same slope but this time solving for b
- y=x+b
- plug in your coordinates
- 0=1+b
- subtract 1 from both sides
- -1=b
- so your equation would be
- y=x-1
