M= y2-y1?x2-x1
m=4-(-1)/(-7)-8
m=5/-15
m=-3
The slope is -3
1. When the lines cross, the form to angles that opposite each other: (2x+2)º and (3x-52)º. By definition, they are "Vertical angles" and are congruent. Then, to find the value of "x", you must follow the proccedure below:
2x+2=3x-52
2. When you clear "x", you obtain:
2+52=3x-2x
x=54º
Therefore, the value of "x" is 54º
Thirty more than x = 30 + x
Slope = Change in Y / change in X
Slope = (8 - 2) / (9-6)
Slope = 6 / 3
Slope = 2
I'm not sure but maybe the answer is :
68 / 74 = 0.919
