Answer:

the answer is No, because the slopes are not the same

Step-by-step explanation:

in the equation: y=6x+9

the slope is 6

in the equation: 27x - 3y= -81

the slope is 7

the slopes are NOT the same

For the 2nd equation, you need solve for y to get it by itself so once thats done you get y=9x+27 but since the x values (also the slope) aren't equal, they can't be parallel

Find the distance between the points (-9,0) and (2,5)

andreev551 [17]

Answer:

sqrt(146)

Step-by-step explanation:

The distance between these two points can be the hypotenuse of our right triangle.

We can create a right triangle with two legs of length 11 and 5. To solve for the hypotenuse, we apply the pythagorean theorem

sqrt(5^2+11^2)=sqrt(146)

I attached a graph to help you visualize the triangle and how it works.
