Question

CANT GET WRONG

The equation y = 4x + 4 describes the relationship between the quantities x and y. Are the quantities in a proportional relationship?
A) Yes, because the graph of the equation is a straight line.
B) No, because the graph of the equation is not a straight line.
C) Yes, because the graph of the equation passes through the origin.
D) No, because the graph of the equation does not pass through the origin.

Answer 1

The correct answer would be D. because if the equation has a y-intercept (+4) than the line doesn't go through the origin.

Answer 2

Option D is correct that is No, because the graph of the equation does not pass through origin.

Explanation:

We have been given the equation:

y = 4x+4

The direct proportion means if equation follow: y=mx where m is the proportion or can say equation passes through origin.

Here, equation is y=mx+c not y=mx

In y=mx

We can see if x increases y will increase

And if x decreases y will decrease.

Therefore, Option D is correct that is No, because the equation does not pass through origin.
