Answer

No solutions See graph below.

Work Step by Step

Given the system of equations: 1. $6x - 8y = 15$ 2. $-1.5x + 2y = -4$ It asks to find all solutions and to graph. Multiply equation 2 by 4, then add it to equation one 1. $6x - 8y = 15$ 2. $-6x + 8y = -16$ $0 + 0 = -1$ $0 = -1$ Since 0 is not equal to -1, then there are no solutions present. The lines are parallel to each other. See graph below. The red line is graph 1; the blue line is graph 2
