Answer:
The first car was traveling 70 mph, while the second was driving 50 mph.
Step-by-step explanation:
Set the cars as a proportion:

X represents the speed of the second car. By cross multiplying, you get the following equation:

You solve by distributing 150 to get 210x = 150x + 3000.
Solving for x gets you 50.
That means the first car was going at 50 mph. Adding 20, you get 70 as the speed for the second car.
I kind a get the answer for this one but I’m not sure if that’s the correct one but I think your answer will be -6
Answer:
y = -1/2x
Step-by-step explanation:
The y - intercept is 0, because the point where the line touches the y - axis is y - value of 0
The slope is -1/2 because as it rises by -10, it runs by 20
Slope is rise/run which is -10/20 which simplifies to -1/2
y = mx + b
b = y - intercept
m = slope
y = -1/2x + 0 or y = -1/2x
