Can someone please help me graph y= -2x+7

Anthony is making a collage for his art class my picking shapes randomly. he has five squares, two triangles, two ovals, and four circles. find p( circle is chosen first)

The graph of a function f(x)=(x+2)(x-4). which describes all of the values for which the graph is negative and increasing? all real values of x where x< -2 all real values of x where -2

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
