Hmm idk if this is what you need, but here we go: Amy is 5 years older than her brother, John. Her age is 19. How old is John?
x-John
x+5=19
x=19-5=14
John is 14.
D:= Driving is difficult
W:= The weather is stormy
The sentence means:
W ==> D
Read as "W implies D"
Which basically just means:
Whenever we have W, we have D, too! Always. We can't have W without also having D.
In this case, we are given W (the weather is stormy). So, we must also have D! (Driving is difficult)
The answer is C.
Your y-intercept is 4 so your first point is on (0,4) and from there you will move down .5 over 1, down .5 over 1
Or you can go and visit desmos.com and type that in there and they will give you a more detailed look of how to do it.
