A line has this equation : y = 9/4x + 9 Write an equation for the parallel line that goes through (12, 7) .
1 answer:
Answer:
y=9/4x-20
Step-by-step explanation:
Do the parallel line equation
7=9/4(12)+b
Solve for b
7=9×12÷4+b
7=27+b
subtract 27 to both sides
-20=b
Parallel lines have the same slope
y=9/4x-20
