Write an equation of the line containing the point (6,-4) and perpendicular to.the line y=-2x-3

igor_vitrenko [27]

Answer:

$y=\frac{1}{2}x-7$

Step-by-step explanation:

So we need to find an equation of a line that crosses the point (6,-4) and is perpendicular to y = -2x -3.

First, let's find the slope of the line we want to write. The line we want is perpendicular to y = -2x -3. Recall that if two lines are perpendicular to each other, their slopes are negative reciprocals of each other. What this means is that:

$m_1\cdot m_2=-1$

Plug -2 for one of the slopes.

$-2\cdot m_2=-1$

Divide by -2 to find the slope of our line.

$m_2=1/2$

Thus, our line needs to have a slope of 1/2.

Now, let's use the point-slope form. The point-slope form is given by:

$y-y_1=m(x-x_1)\\$

Plug in 1/2 for the slope m and let's let our point (6,-4) be x₁ and y₁. Thus:

$y-(-4)=\frac{1}{2}(x-6)\\$

Simplify and distribute:

$y+4=\frac{1}{2} x-3$

Subtract 4 from both sides:

$y=\frac{1}{2}x-7$

The above is the equation that passes the point (6,-4) and is perpendicular to y = -2x -3.

B) However, on Harry’s eleventh birthday, he learns from a mysterious stranger, Rubeus Hagrid, that he is actually a famous wizard.

C) Forbidden by his uncle from seeking out his magical destiny, letters rain down inviting Harry to attend the magic school of Hogwarts.

D) What follows is an adventure story of intrigue, discoveries, and sacrifice.

In order of events:

A, C, B, D

A is where the story begins so it would be the best chose. It should catch you and make you want to know more. Also, the hook is usually the first sentence.

How many line of symmetry does a hexagon has?

yaroslaw [1]

Since it is a hexagon and it has 6 sides (and we assume it is regular since it doesn't tell us otherwise) then the hexagon will have 6 lines of symmetry (:
