To find slope:
(y1 - y2) / (x1 - x2)
(0-3)/(-4-0)
Slope is 3/4
So the equation is
y=3/4x + 3
The total area of the given composite figure is; 84.8 ft²
<h3>How to find the area of a composite figure?</h3>
We are given;
Area of triangle = 5.6 ft²
Thus, area of 2 triangles = 2 * 5.6 = 11.2 ft²
Area of rectangles = 2(3.6 * 2) + 2(2 * 4) + 3(4 * 3.6)
Area of rectangles = 14.4 + 16 + 43.2
Area of rectangles = 73.6 ft²
Total Area of composite figure = 73.6 ft² + 11.2 ft²
Total Area of composite figure = 84.8 ft²

Answer:
k = -1
Step-by-step explanation:
-3k + 6 = 10 + k
combine similar terms:
-3k - k = 10 - 6
simplify:
-4k = 4
simplify:
k = 4 / -4
k = -1
