Write the equation of a line perpendicular to y=-2x+1 that passes through the point (2,3)
Cloud [144]

Answer:

y = 1/2x + 2

Step-by-step explanation:

First you have to determine the slope which is the opposite reciprocal of the slope of the line given.

So we take the slope -2 and reciprocate and by flipping the numerator and denominator which makes it -1/2.

Then we have to make it the opposite, like making a negative into a positive or a positive into a negative. So that would make it positive 1/2.

We now have the slope which is 1/2 and not we have to make sure it goes through point (2,3).

To do that, we must adjust the y-intercept until it goes through that point. We result in getting the y-intercept of 2.

The answer is y = 1/2x + 2

zzz [600]
Firstly we need to count what is the difference between both altitudes:

44,000 - 9,000 = 35,000

If a plane descends at a rate of 2,500 feet per minute, then we have to count how many 2,500s fit in 35,000:

35,000 / 2,500 = 14

It means that the jet will reach its cruising altitude in 14 minutes.
