Let t be time in hours.
Train A travels at 100 km per hour, so after t hours it will be 100t km from the station.
Train B travels at 160 km per hour, but it leaves the station one and a half hours later than train A, so its time is (t-1.5) hours. After (t-1.5) hours it will be 160(t-1.5) km from the station.
Train B will overtake train A when their distances from the station are equal.

Train B will overtake train A after 4 hours since train A left the station. It left the station at 8:00, so train B will overtake it at
12:00.
The y-intercept is found when x is set to 0.
Set x to equal 0 for both equations:


Divide both sides by -2:

The y-intercept of this equation is 3, so the first line does not have the y-intercept of -2.
-


Divide both sides by 2:

The y-intercept of this equation is -1, so the second line does not have the y-intercept of -2.
Neither line has a y-intercept of -2.
Answer:
y = -3x-1 or 3x + y = -1
Step-by-step explanation:
6x + 3y - 11 = 0 can be written as y = -3x + (11/3)
In parallel lines the slope remains the same but the constant changes. To find the constant you place in the cordinates for x and y.
5 = -3(-2) + b
5 = 6 + b
5 - 6 = b
-1 = b
Now you replace (11/3) by the new b, -1
y = -3x - 1
