The equation of the line that passes through 2 points is
%28y-y%5B1%5D%29%2F%28y%5B2%5D-y%5B1%5D%29=%28x-x%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
Substitute
x%5B1%5D=6, y%5B1%5D=8, x%5B2%5D=-8, y%5B2%5D=-6
%28y-8%29%2F%28-6-8%29=%28x-6%29%2F%28-8-6%29
%28y-8%29%2F-14=%28x-6%29%2F-14
y-8=x-6
y=x%2B2 an equation of the line
The slope-intercept form of the equation is y=mx%2Bb
the slope m=1
Answer: m=1
