Two passengers leave the airport at Kansas City, Missouri. One flies to Los Angeles, California, in 4 hr and the other flies in the opposite direction to New York City in 5 hr. With prevailing westerly winds, the speed of the plane to New York City is 50mph faster than the speed of the plane to Los Angeles. If the total distance traveled by both planes is 2464mi, determine the average speed of each plane.

Speed of plane to Los Angeles: 400 miles per hour

speed of plan to new York city: 460 miles per hour

a. is correct

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
