What is the distance between the points 3, 7 and 15, 6 on a coordinate plane

Step-by-step explanation:

We are actually using Pythagorean theorem here but to be simple

we can use the equation:

D(distance)=

=

(If you meant 16 instead of 6 the answer would be 15)

Hope this helps!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
