Answer:

P(-2,7)

P'(-2,-7), ANSWER

reflection across the x-axis rule:

(×,y) ===> (x,-y)

Easy way to do this is draw the point on graph paper and count the same units above/below the x-axis. This example you are 7 units above the x-axis so you would count 7 units below the x-axis giving you the point.

How to write y-6=-5/2 (x+4)
coldgirl [10]

Answer:

In point slope form, this is y = (-5/2)x + 2.  In standard form, it's (5/2)x + y = 2.

Step-by-step explanation:

y-6=-5/2 (x+4) has already been written in point-slope form.  The slope of the line is -5/2 and the point on the line is (-4,6).

In slope-intercept form:  add 6 to both sides of the original equation, obtaining y = 6 - (5/2)(x + 4), or y = 2 - (5/2)x, or y = (-5/2)x + 2

Answer:

the equation will be:

\mathbf{x-5=3}

solving the equation we get x=8

Option B is correct.

Step-by-step explanation:

We need to write equation for this sentence:

The difference between a number and five equals three.

Let number = x

So, the equation will be:

\mathbf{x-5=3}

Now, solving the equation to find value of x

x-5=3

Adding 5 on both sides

x-5+5=3+5\\x=8

So, solving the equation we get x=8

Option B is correct.
