I need help with this please

Write a real-world solution that can be represented by the equation y = 7x be sure to explain what the variables represented in the solution

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex

Graph the equationy=x^2 -[tex]y = x^{2} - 2[/tex]
