Determinate whether the graph of the given equations are parallel, perpendicular or neither 1. y=x+11 y=-x+2 2. y=-2x+3 2x+y=7 3. y=4x-2 -x+4y=0

What will the graph look like for a system of equations that has no solution? a. the lines will be perpendicular. b. the lines will cross at one point. c. both equations will form the same line. d. the lines will be parallel.

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
