In order to find the slope of your line, we must first get it into y=mx+b.-9x-7y = 8-9x + 9x - 7y = 8- 7y = 9x + 8-7y/7 = 9x/7 + 8/7-y = 9x/7 + 8/7(-1) -y = 9x/7 + 8/7y = -9x/7 - 8/7The slope is -9/7 and the y-intercept is -8/7

The expression (9x 7)-(x 3) can be simplified as follows: (9x - 7) - (x - 3) = 9x - 7 - x + 3 = 8x - 4
(9x2 + 7)(9x2 - 7) = 81x4 - 49
11 + 9X
x=-7
The slope intercept form is: y = mx + b 9x + 7y = 15 9x - 9x + 7y = 15 - 9x 7y = - 9x + 15 y = -(9/7)x + 15/7
63x/49 = 9x/7
X = 7 9x - 2x = 49
If you mean 9x -7 = -115 then the value of x is -12
X = 7 9x - 2x = 49
9x - 20 = 7 9x = 27 x = 3
