Slope of the line through the points (11, -2) and (0, 0)



m+=+%28y%5B2%5D+-+%28y%5B1%5D%29%29%2F%28x%5B2%5D+-+x%5B1%5D%29


m+=+%280+-+%28-2%29%29%2F%280+-+11%29


m+=+%280+%2B+2%29%2F%280+-+11%29


m+=+%282%29%2F%28-11%29


m+=+-2%2F11



Answer: Slope is m+=+-2%2F11



now, when we know the slope m=-2%2F11 and points a line passing through, we can find equation of that line
Solved by pluggable solver: Find the equation of the line(with graph)---slope a nd y-intercept:given

Using the slope-intercept form,
y=mx%2Bb
where m=slope, b=y-intercept,
and, substituting the values m=-(2/11) and b=0,
y=%28-%282%2F11%29%29x%2B0
And the general equation is,
%28-%282%2F11%29%29x-y%2B0=0

Slope = (-2 - 0)/(11 - 0) = -2/11
