Answer: a= -2
Step-by-step explanation:
its a = minus 2
So y=12x. All you need to do is plugging in x=3;
y = 12(3) = 36
So answer is B.
<u>Answer-</u>
The equation that describes the pattern is,

<u>Solution-</u>
P = Number of minutes Rodney spends practicing playing the piano
G = Number of minutes Rodney spends practicing playing the guitar
Taking P on x axis and G on y axis, the points are,

Taking first two points i.e
, the line equation will be,






Putting the other two points i.e
in the equation, they also satisfy the equation. That means they are also on the same line
.
From the result, it is evident that P and G are linearly related.
Acc. to midpoint theorem,
15={(2x+9) + (4x-15)}/2
⇒ 30=2x+9+4x-15
⇒ 30-9+15=6x
⇒ 36/6=x
⇒6=x
WZ= 4x-15
=4*6-15
=24-15=9
