(PLEASEEE HELP I DONT UNDERSTAND) Which of the following equations represents a linear NON-proportional function? A) y=3x+0
B) y=x/4
C) y=7x
D) y=2/5x+7

D

A nonproportional relationship is a linear line that doesn’t go through the origin.

y=3x+0 does go through the origin because the y-intercept (the b) is 0

Y=x/4 also has a y-intercept of 0

Y=7x also has a y-intercept of 0.

y=2/5x+7 does not go through the origin because the line passes the y-axis at (0,7) which is the y-intercept.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
