Answer:
Step-by-step explanation:
To find the distance between two points,
and
, you can use the following distance formula:

Plugging in the points from the problem, you'll get the following:





Answer:
Step-by-step explanation:
y - y1 = m(x - x1) y1 = 1 x1 = 2 m = -1/3
y - 1 = -1/3(x - 2)
y = -x/3 + 2/3
The correct answer is C.) c=5
This is correct by using the equation c^2=a^2+b^2
c^2=3^2*4^2
c^2=9+16
c^2=25
Square root of c=square root of 25
c=5
