Answer:
y = 2x -19
Step-by-step explanation:
Put 3 and -13 as values of x and y and see which equation remains true. i.e Left side - right side. That is your answer
Option A
y = 2x -19
Put values
-13 = 2 (3) -19
-13 = 6 - 19
-13 = -13
Rest of equations do not. You may check on your own so option A is answer.

Answer:
Step-by-step explanation:
The team draws with a probability of 1 = (0.5 + 0.2) = 0.3
If the team does not win then it loses or draws.
Loosing = 0.2
Draw := 0.3
P(not win) = 0.2 + 0.3 = 0.5
======================
Not lose means wins or draws.
P(not lose) = 0.5 + 0.3 = 0.8
======================
Not Draw means wins or loses
P(not draw) = 0.5 + 0.2 = 0.7
Of course all of these could be done more directly.
P(not win)= (1 - win) = 1- 0.5 = 0.5
P(not lose) = ( 1 - lose) = 1 - 0.2 = 0.8
P(not draw) = (1 - 0.3) = 0.7
