if you divide the figure in parts, you will have two rectangles 1 of an area of 100 - 8(the area of the triangle in the bottom ) and the other rectangle with an area of 225 but is a triangle so you divide by two = 112.5 soy the total area is 92+ 112.5 = 204.5
a. y = -1x +4
b. y = 1x +8
for a it intercepts 4 for y. as you can see, it k intercepts with j at (-2,6). it is moving 2 to the left and 2 up. when you use rise over run, x equals -1/1 (because you move from left to right).
hopefully this you.
