Question

Which equation represents a direct linear variation? A.


B. y = x + 2

C. y = x2

D. y = ½x

Answer 1

a is y=1/x

Answer 2

ok well a direct linear variation means that it must be a straight line and it must pass through the origin. so c is out because that curves. a is out because x can't be zero. and b is out because it crosses the y axis at 2 instead of zero. c is the correct answer

Answer 3

but I thought c is out because it curves

Answer 4

my mistake I meant D
