The total surface area is 121.8yd^2 and the lateral surface area is 79.8yd^2.
121.8 - 79.8 = 42

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following equation:

So:
, the slope is positive

For the graph, we place the point on the coordinate axis:

We draw the line!
The graphic is attached.
ANswer:
, the slope is positive

Answer: -4. Reasoning: We are trying to get the angle of both lines to equal 180. If you add 60+124 together to see how much we have currently, your answer comes up to 184. That’s 4 over what we need, therefore, -4 would be needed to bring the current amount back down to 180.
