Line bc has an equation of a line y = 2x + 3, and line ef has an equation of a line y = negative one over 2x + 4. these two equations represent

a. parallel lines because the slopes of the lines are equal
b. perpendicular lines because the slopes are opposite reciprocals
c. the same line when graphed
d. lines that intersect, but not at a right angle

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
