Answer:
we have to factories it in both activities..
Angles on a straight line add up to 180°, so:
x + 60 = 180
x = 180 - 60
x = 120°
Hi there! The answer is C.
We can find the slope of this line by making y the subject of the equation.

Now we can see that the slope of this line (which is positioned in front of x) is 3/4. Therefore, the slope of any line parallel to this one is 3/4 as well. The answer is C.
It’s a reflection across the x-axis
