The coordinate grid shows the plot of four equations. a coordinate plane is shown with four lines graphed. line a crosses the x axis at negative 3.5 and the y axis at 7. line b crosses the x axis at 6.5 and the y axis at 4.5. line c is horizontal and crosses the y axis at 1. line d crosses the x axis at 0.5 and the y axis at 1.which set of equations has (−1, 5) as its solution? a and b b and d a and c b and c
