Point slope form:
m=slope
(x1,y1)
First we need to find the slope using the slope formula:
Given the two coordinates:
<span>(1, 9) and (−1, 11)
Plug them into the slope formula:
</span>
Simplify:
<span>
Now we know that:
m=-1 and the (x1,y1) would be </span><span>(1, 9)
</span>
Now we simply plug in the info:
Final answer: y − 9 = −(x − 1)
m=slope
(x1,y1)
