Answer:

y = 2x + 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (- 4, 2 ) into the partial equation

2 = - 8 + c ⇒ c = 2 + 8 = 10

y = 2x + 10 ← equation of line

slega [8]

Answer:

$ry=\frac{rx}{2\pi }$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

Circle X

$rx=6\ units$

$Cx=12\pi\ units$

Circle Y

$Cy=6\ units$

Find the radius ry

we know that

$Cy=2\pi ry$

substitute the value of Cy

$6=2\pi ry$

$ry=\frac{6}{2\pi }$

Remember that the value of rx is $rx=6\ units$

substitute

$ry=\frac{rx}{2\pi }$
