Which line represents the direct variation equation y = 1/2x? line a. line b. line c. line d.

C.

Step-by-step explanation:

y = 1/ x must pass through the origin because when x = 0, y = 0.

So its either B or C.

A positive slope rises to the right ( 1/2  is positive), so its C.

You can also see that the slope of C is 1/2 because it passes through the points (0.0) and (2, 1).

Line C

Step-by-step explanation:

the slope is 1/2 so change in y/ change in x which means 1 is the y and 2 is the x.

the y-intercept is 0.

So up 1 right 2 starting from the origin (0,0)

3x + 4y -25 =0 represents the amount of change sianna should recieve

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
