So the answer will be A
OpenStudy (anonymous):
A? CAN YOU EXPLAIN WHY?
OpenStudy (anonymous):
If a line is drawn through y = 1, you can plot any points on x but the y point will always be a 1. This makes a straight, horizontal line. The change in y is 0 since y is always 1 and 1-1 = 0. Any fraction with a 0 in the numerator = 0, no matter what number is on the bottom, right? So if there is no change in the rise, the line is horizontal.
OpenStudy (anonymous):
Wow, you can also think of it as whenever a line is equal to x its vertical. and whenever it is equal to y its horizontal?

Not you.. Don't worry about it. Anway, we know that the answer is either B or D, but now we need to figure out wether the slope is zero or undefined.
OpenStudy (anonymous):
Zero slope looks like this: 0/5 Undefined slope looks like this: 5/0
OpenStudy (anonymous):
i think its D? IM RIGHT?
OpenStudy (anonymous):
yup : )
OpenStudy (anonymous):
Good job

Which of the following lines is parallel to x = 4?
3y = 9
y = 4
x = 2
x = y
OpenStudy (anonymous):
i choose B
OpenStudy (anonymous):
Okay, well we know that the line X=4 is vertical, but...the line y=4 is not horizontal. For a line to be parallel to the line x=4 it needs to follow the format x= ???
