Answer:
7, 24, 26
Step-by-step explanation:
6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)
Answer: The slope (m) of the line using two points where the line goes through is:
m = - 4 (negative 4).
Solution:
m=(y2-y1) / (x2-x1)
Taking two points in the graph where the line goes through:
P1=(0,2)=(x1,y1)→x1=0, y1=2
P2=(1,-2)=(x2,y2)→x2=1, y2=-2
Replacing in the formula of the slope:
m=(-2-2) / (1-0)
m=(-4) / (1)
m=-4
