Question

Which function has the same y-intercept as the line graphed below?

Answer 1

Answer: D(y=4=2x) is Correct

Explanation:

We wanna set x=0 because when we have our y-intercept, we wanna set x=0.

*y=16-3x/4 is a positive 4 and the graph shows a -4 so A is incorrect.

*24+3y=6x ----> 3y/3=-24/3=y=-8 so B is incorrect

*4y+x=16 ---->y=4 so C is incorrect

y=-4

*y+4=2x is the only one left so D is Correct.

Answer 2

The correct answer is D. y = 2x - 4.

This is because as you can see from the graph that the y intercept comes out to be - 4.

And now as we know that the basic line of equation general form is y = mx + c where c is the y intercept.

So if we follow this and rearrange the last equation we get it as y = 2x - 4 where c is -4 m is 2 and x and y are the same.
