Yes it an obtuse because the angle is 110
and its isosciles becaues the two 35 angles
To construct the equations for these lines, we are going to use the point-slope formula, which is:

is the slope of the line
is a point on the line
1)
In this case, our point is (2, -1) and our line has a slope of 5. (Remember that the line is parallel, meaning that it has the same slope as the given line. Since the line is in the y = mx + b format, we could easily pick out the slope m as being 5.)
Thus, we can "plug in" what we know into our formula to find the equation of our line:



2)
We are going to do the same thing, except our point is now (0, -5) and our slope is now 9.


Our equations are:
1) y = 5x - 11
2) y = 9x - 5
Answer:
18(x - 3)
Step-by-step explanation:
18x - 54 ← factor out 18 from each term
= 18(x - 3)
