Given:

There exist a proportional relationship between x and y.

To find:

The equation which represents a proportional relationship between x and y.

Solution:

If there exist a proportional relationship between x and y, then

y\propto x

y=kx

where, k is constant of proportionality.

We know that, proportional relationship passes through the origin because (0,0) satisfy y=kx.

For x=0, check which equation has y=0.

In option A, y=-3(0)-2=-2.

In option B, y=9.

In option C, y=4(0)=0.

In option D, y=3(0)+1=1

Only in option C, we have a equation of the form y=kx with 4 as constant of proportionality and it passes through (0,0).

Therefore, the correct option is C.

The point (-3, 4) is on the line x+4y=13.
lys-0071 [83]

Answer:

yes

Step-by-step explanation:

To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line

- 3 + (4 × 4) = - 3 + 16 = 13 = right side

Hence (- 3, 4) lies on the line x + 4y = 13
