The slope of a line is
. We have the points (3, -2) and (1, 8). Let's substitute those into the formula.
subtracting a negative is the same as adding, so that makes our equation
slope = -5
3(x-k)/w = 4
3x - 3k/w = 4 is the answer.
No value is given for x, k or w.

Answer:
Step-by-step explanation:
Remember that the formula to get the area of a right triangle is base times height divided by 2, so to find the area:
5 x 12 = 60/2 = 30
Area of this triangle is 30.
To find the perimeter, add all the sides:
5 + 12 + 13 = 30.
Perimeter of this triangle is 30.
