Answer:
Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
-y₁ + y₂\-x₁ + x₂ = m
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y - 9 = -8(x + 6)
y - 9 = -8x - 48
+ 9 + 9
______________
y = -8x - 39
__________________________________________________________
y + 7 = -8(x + 4)
y + 7 = -8x - 32
- 7 - 7
______________
y = -8x - 39
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

We know that angle 101 and its interior angle next to it will equal 180 because it's a straight line.
180-101= 79 degrees
Find 3rd angle of triangle.
180= 38+79+y
180= 117+y
Subtract 117 from both sides
63= y
That is the interior angle by x. X plus 63 also equal a line, or 180 degrees.
180= 63+ x
Subtract 63 from both sides
117= x
Hope this helps! :)
