Answer:
B
Step-by-step explanation:
The study doesn't prove a causation, only a correlation. So we can conclude that cities with good air quality do not have traffic jams.
Hello!
You can put x into the answer choices to see if we get y
----------------------------------------------------------------------------------------------------
y = -x + 9
y = -(-5) + 9
y = 5 + 9
y = 14
This could be a answer
y = -(-2) + 9
y = 2 + 9
y = 11
y = -(1) + 9
y = -1 + 9
y = 8
y = -(4) + 9
y = -4 + 9
y = 5
we got y every time so the answer is the first one
The answer is A) y = -x + 9
Hope this helps!
The answer is a=-3. just add the -2 and the 3 so that would be a+1=-2 then subtract the 1 from both sides to get the a alone.
Answer:
y=3x-5
Step-by-step explanation:
parallel means that both lines share the same gradient.
from the equation y=3x-12 , we can deduce that the gradient is 3 because it is in the gradient-intercept form
now substitute values into formula
y-y1=m (x-x1)
y--2=3 (x-1)
expand brackets and simplify
y+2=3x-3
subtract 2 from both sides of equation
y=3x-5
