Consider a graph for the equation y= -3x+4. what is the y intercept? a) 4 b) -4 c) 3 d) -3

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.

The graph represents this system of equations: 2x + y = 3 2x - 5y = 15 what is the solution to the system of equations represented by the graph? (0, -3) (1,1) (1.5,0) (2.5, -2)
