Find the equation of the straight line passing through the points (4; 2) and (2; 4).
Alecsey [184]
Use point-slope form.

But first let's find the slope.

(4, 2), (2, 4)

m = y2-y1/x2-x1

m = (4 - 2)/(2 - 4)

m = 2/-2

m = -1

So this is the slope, now we can plug this into the equation along with any point.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

Let's plug in point (4, 2):

y - 2 = -1(x - 4)

This can be one of your options.

Distribute -1:

y - 2 = -x + 4

Add 2 to both sides:

y = -x + 6

This can be another of your options.

Add 'x' to both sides:

x + y = 6

This can be another of your options.

A small plane is 20 miles due north of the airport. a jet at the same altitude as the plane is 64.5 miles west of the airport. t
podryga [215]

okay realize that the distance traveled by the small plane, distance traveled by jet, and the distance between them makes a right triangle. Using Pythagorean theorem and allowing x be the distance between them, x² = (20 miles)² + (64.5 miles
 x = 67.53 miles the distance between the two entities in nearest tenth is approximately 67.5 miles.

a student used his place value chart to show a number after the teacher instructed him to divide his number by 100 the chart sho
Anna35 [415]
<span>A student divided the given number by 100 that resulted to 28.003 in his chart. So what we are looking for this situation is the value of the number before it was divided by 100.
To get the value, simply multiply the result by 100
=> 28.003 x 100
=> 2800.3
 by dividing 100 to the given number, we simply move the value to the right in a value of hundreds.
See attached Image.
