Write an equation for the line that is parallel to y = −2x and passes through the point (0, −7).

y = -2x -7

Step-by-step explanation:

Parallel lines have the same slope

y = -2x has a slope of -2

The parallel line will have a slope of -2

It goes through a point of (0,-7).  This would be the y intercept

y = mx+b

y = -2x -7

y=-2x-7

Step-by-step explanation:

y = −2x, then slope=-2.

The lines are parallel so the slope is the same.

(0,-7)x1 =0,y1=-7

y-y1=-2(x-x1)

y-(-7)=-2(x-0)

y+7=-2x

y=-2x-7

answer: haha (: i’ll go see what it is

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
