check my answer please? question in the comments.

Directrix (directrix):

The option you chose has a negative slope which indicates that the line is falling.

Directrix (directrix):

The line you are given is rising.

OpenStudy (anonymous):

the option is D then?

jimthompson5910 (jim_thompson5910):

`negative slope` ----> line goes downhill as you read from left to right |dw:1458438742229:dw|

OpenStudy (seratul):

It can't be D. The y intercept is at Positive 4. Try again.

OpenStudy (anonymous):

so it's c.. i don't understand that at all but ok..

Directrix (directrix):

y = 4x + 4. Let x = 0. y = 4*0 + 4 = 4 That gives the ordered pair (0,4) Look on the given graph. Does the given line pass through the point (0,4)? If so, then that is the correct option.

OpenStudy (seratul):

Y intercept (the number without a variable) is where the line meets the y axis. In this option, it is at positive 4. The slope with the variable it how much it rises and how much it runs. In this option, it is 4x. Like said above in the comments, it is a positive slope. So yes, it is C.
