You need to split the shape into simpler shapes so you would get a rectangular prism and a triangular prism finding the volume is pretty straightforward the formula is
Volume of a triangular prism = area of base triangle × height
The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W.
After solving for this you would just have to add the 2 shapes volume together tie get the volume of the composite figure
Finding the surface area is also pretty simple since it would only require you to know the formulas
S = 2(lw + lh + wh) to find the surface area of a rectangle or prism
A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
And by adding the two surface areas of the shapes you can get the surface area of the composite figure but remember to subtract the top face of the rectangular prism and the bottom face of the triangular prism

Answer: See below
Step-by-step explanation:
For the line on top, we know the slope is negative because it is going down. We can find the slope by counting how much the point goes down and to the right. Y-intercept is the point on the y-axis.
slope: -3
y-intercept: 2
Now that we have the slope and y-intercept, we know the equation is y=-3x+2.
For the second line, we know the slope is positive because it is going up. Since slope is rise/run, we can see it rises 1 unit and runs to the right by 2 units. Y-intercept is the point on the y-axis.
slope: 1/2
y-intercept: -5
With our slope and y-intercept, we know our equation.
y=1/2x-5
