Find the equation of the line in the xy-plane that contains the point (9, 3) and that is parallel to the line y = 6x – 4.

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

Icould really use some with this question.

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
