Question

For a science experiment Corrine is adding hydrochloric acid to distilled water. The relationship between the amount of hydrochloric acid, x, and the amount of distilled water, y, is graphed below.

Answer 1

Which inequality best represents this graph?

2y − 3x < 0

3y − 2x < 0

2y − 3x > 0

3y − 2x > 0 @ganeshie8

Answer 4

dashed line means < or > (as opposed to ≤ or ≥ )
but all your choices use < so that does not help

Answer 5

I got D... am i correct ?

Answer 6

you can look at the dashed line and figure out is slope 4/6 = 2/3
the line goes through (0,0) . it 's equation is
y - 0 = (2/3 x - 0 or just y = (2/3) x
multiply both sides by 3

3y = 2x
or
2x - 3y = 0

Answer 7

or 3y - 2x =0

we see the area above the line is shaded. we want y > 2/3 x or 3y -2x > 0

Answer 8

37 - 2x > 0

Answer 9

3y****

Answer 10

yes, that is what I got
