Line AB contains points A (-1,3) amd B (5,3). Line AB has a slope

Hello!

To calculate the slope given two points, we use the formula y2-y1/x2-x1. You can switch the ones and twos and the slope will be the same. We will have (-1,3) represent (x1,y1) and (5,3) represent (x2,y2).

Now we plug these numbers into the equation.

3-3/5+1
0/6
Undefined

Since the number is divided by zero, the slope is undefined, or the line is vertical. Just to check, we will switch the ones and twos.

3-3/-6
0/-6
Undefined

Our line is vertical, therefore our slope is undefined.

I hope this helps!

Ilya [14]

Answer:

No Real Solutions.

Step-by-step explanation:

√(x-5)=8√(x-2)

Square on both sides,

(√(x-5))^2=(8√(x-2))^2

or,(x-5)=64(x-2)

or,x-5=64x-128

or,-5+128=64x-x

or,123/63=x

Therefore, x=41/21

If you plug x=41/21 in √(x-5)=8√(x-2) you do not get equals, so the problem has no real solutions.
