Answer:
y=-5x-21
Step-by-step explanation:
So the slope will be the same, rewrite the equation with the same slope and substitute in the coordinates. Then, solve for b.
y=mx+b
-1=-5(-4)+b
-1=20+b Subtract 20 from each side
-21=b
The equation is y=-5x-21
Answer:
60 mph
Step-by-step explanation:
mph=miles/hours
240/4=60
60 miles per hour
5x – 1 = 3x – 15
Subtraction Property of Equality (Subtract 3x from both sides)
2x - 1 = -15
Addition Property of Equality (Add 1 to both sides)
2x = - 14
Division Property of Equality (Divide both sides by 2)
x = -7
