Find each slope. Round to the nearest tenth. A 2-dimensional graph with an x-axis and a y-axis is given. Six straight lines, a, b and c are parallel to each other and lines d, e, and f are parallel to each other and perpendicular to lines a, b and c. Line a is passing through the co-ordinates (-3,0). Line bis passing through the co-ordinates (-2,0). Line c is passing through the co-ordinates (2, 0). Line d is passing through the co-ordinates (0, -2.5). Line e is passing through the co-ordinates (0,-1) and line f is passing through the co-ordinates (0,2) respectively. The lines intersect with each other at several points. slope of c = slope of e = slope of d =
