Question 102878
Let's define Point 1 as (-7,5) and Point 2 as (2, -3).
.
Then you can say that {{{x[1] = -7}}} and {{{x[2] = 2}}}
.
Similarly you can say that {{{y[1] = 5}}} and {{{y[2] = -3}}}
.
Then the equation for the slope (M) is:
.
{{{M = (y[2] - y[1])/(x[2] - x[1])}}}
.
Now all you have to do is substitute the values identified above to get:
.
{{{M = (-3 - 5)/(2 -(-7)) = -8/(2 + 7) = -8/9}}}
.
So the slope is {{{-8/9}}}
.
Hope this helps you to see your way through the problem.
