What is the slope? What is the y intercept?
What is the equation of the line written in slope-intercept from?

Step-by-step explanation:

As we move along the graph from x = 2 to x = 3 (a change of 1), y decreases from y = 100 to y = 0 (a change of -100).  Thus, the slope of this line is

m = rise / run = -100/1 = -100.

The y-intercept is the point where the graph crosses the y-axis, and is (0, 200).

The equation of this line in slope-intercept form is  y = -100x + 200

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
