Answer:
X=-7/5 and y= 8/5
The slope of both lines is infinity
<h3>Slope of a line</h3>
The formula for calculating the slope of a line is expressed as;
Slope = y2-y1/x2-x1
Given the coordinate (-7, -9) and (-7, 8).
Slope = 8+9/-7+7
Slope = 17/0
Slope = infinity
For the coordinate points (8, 5) and (8, -5).
Slope = -5-5/8-8
Slope = -10/0
Slope = infinity
Hence the slope of both lines is infinity
