Answer:

14

Step-by-step explanation:

if b=4 and a=2, then you substitute both those values into the equation, turning (4b - a) into (4*4 - 2), then you use order of operations, meaning you multiply the 4 times the 4, which turns it into 16-2, and then subtract 2 to finally reach your answer of 14.

Which line represents the direct variation equation y equals 1/2 x
damaskus [11]

Answer:

line c

Step-by-step explanation:

The graph representing a direct variation equation always passes through the origin. This could be graphs (a) or (c)

given y = \frac{1}{2} x

with slope = \frac{1}{2}

Since graph (a) slopes down from left to right it's slope is negative

Hence it is not graph (a) as the slope given in the equation is positive.

Hence the required graph is (c)
