How Do You Understand Slopes and Calculate Overlapping Areas?

[skan]

I am having troubel understanding slopes. I know the slope formulas but when given a triangle function, say on the x-axis one end of the base of the triangle is at -2 and the other end at 2 and on the y-axis they converge at 2.

and given a rect function, and when asked to find the area of overlap between the rect and triangle function, I multiply the amplitude or height of the rect function with what of the triangle function?

thanks a lot.

1. What is the slope formula ? You just have to plug in the numbers to find the slopes.

2. No, you draw a picture and figure out the shape of the overlapping figure. Find out the dimensions of this shape and calculate its area.
