which of the following lines is parallel to x=8?
3y=16
x=7
x=y
y=8
select the equation of the line that passes through the points (5,7) and is perpendicular to the line x=4.
y=4
x=5
y=7
x=7

The answer to question #1 is x = 7

For a line to be parallel to x = 8, it has to start with x = some number. Such a line would have an undefined slope.

Now, x = y is a line that goes through the origin. It has a slope of 1.

The answer to question #2 is y = 7

If a line is perpendicular to x = some number, then it has to be y = some number.

And this perpendicular line has to go through the point (4,7). So what is the y-value of this point, since the equation starts with y? The y-value is 7. So the equation has to be y = 7
