ANSWER -
To find the value of k, we can use the slope-point form of a line, which is y-y1=m(x-x1), where m is the slope, (x1,y1) is a point on the line, and (x,y) are the coordinates of any other point on the line.
First, we'll find the slope m=-1 by using the two points:
m = (y2-y1)/(x2-x1) = (-2-4)/(3-k) = -1
Expanding the numerator, we get:
-6/(3-k) = -1
So,
-6 = -1 * (3-k)
Expanding the right side, we get:
-6 = -3 + k
Adding 3 to both sides, we get:
-3 = k
Therefore, the value of k that satisfies the equation is -3.
