The answer is a because you add the same variables and 5x stays the same
Answer:
y=3x-5
Step-by-step explanation:
parallel means that both lines share the same gradient.
from the equation y=3x-12 , we can deduce that the gradient is 3 because it is in the gradient-intercept form
now substitute values into formula
y-y1=m (x-x1)
y--2=3 (x-1)
expand brackets and simplify
y+2=3x-3
subtract 2 from both sides of equation
y=3x-5
Answer:
i dont know sorry :/
Step-by-step explanation:
Answer:
y=2x-8
Step-by-step explanation:
Okay to start this out. You started hiking at 1 P.M. You are at an elevation of 6000 ft. At 5 PM You are at an elevation of 4800 feet. 6000 feet - 4800 feet = 1200 feet in 4 hours.
Make a ratio 4(Hr):1200 Ft
3(Hr):900 Ft
2(Hr):600 Ft
1(Hr):300 Ft
So at the end of the equation your hourly change is -300 ft, because the elevation is going down.
