Let us assume that the unknown number is x.
"2 times the sum of a number and 5" means 2(x + 5).
"the sum of 2 times a number and 5" means 2x + 5.
Therefore, the above statements do not have the same mathematical meaning.

Answer:
Slope (m) = -1
Step-by-step explanation:
(2,1);(0,3)
(x1,y1)=(2,1)
(x2,y2)=(0,3)
Use the slope formula:
m = y^2 - y^1 / x^2 - x^1
= 3-1/0-2
=2/-2
=1
