Write the equation of the line that passes through (3,6) and is parallel to y = 2/3x+2.
aleksley [76]

Answer:

y=\frac{2}{5}x-5

Step-by-step explanation:

y=\frac{2}{3}x+4

the line parallel  to this line is

y=\frac{2}{3}x+k ; k ∈ R

the line passes through the point (3,6)

so,

6=\frac{2}{3} (3)+k\\6=2 +k\\k=4

∴the line that passes through point (2, -1) and is parallel to the line described y = (2/3)x - 6 is

y=\frac{2}{3}x+4

E graph shows the altitude of a helicopter over time.
DaniilM [7]

Let

x-------> the time

y-------> the altitude of a helicopter

Step 1

<u>Find the slope of the line</u>

we know that

the slope m of the line between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

we have

(x1,y1)=(0,10,000)\\(x2,y2)=(15,4,000)

substitute in the formula

m=\frac{(4,000-10,000)}{(15-0)}

m=\frac{(-6,000)}{(15)}

m=-400\frac{feet}{minute}

therefore

<u>the answer is the option </u>

The slope is -400 . This means that the helicopter descends 400 ft each minute.
