The slope is m = rise/run
m = ( -3 - 6 ) / ( 5 - ( -2 )) = -9 / ( 5 + 2 ) = - 9/7
Answer: the slope of the line is -9/7.
Answer:
ohh hiiii...................
the place value of the 9 is the ten thousandths
6x + 15 = 6 (x + 3)
6x + 15 = 6x + 18
6x = 6x + 3
0 = 3
So, there are no solutions to this equation.
Answer:
2, I think. Lines 1 & 2 and lines 7 & 4 are perpendicular
edit: 3 pairs, 3 & 5 is the last one
