Answer:
The distance is
or
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
Answer:
y = 9/b
Step-by-step explanation:
by = 9 solved for b yields y = 9/b.
base times height divided by 2
8 time 6 is 48 divided by 2 is 24
