First solve the equation by dividing 5 on both sides...
Y = 5\2x + 2
Now we want perpendicular and the line to flip across the axis so the answer is....
Y = -2\5 + 2
5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4
4 5/8 = 37/8
2 7/8= 23/8
37/8-23/8=14/8=1 6/8=1 3/4
The answer is #2 you’re welcome
