Answer:
Any line with the slope of 2/3 would be perpendicular.
Step-by-step explanation:
To find this, first solve the equation for y.
-2y = 3x + 7
y = -3/2x - 7/2
Perpendicular lines always have opposite and reciprocal slopes. Therefore, we flip the slope in the original equation (-3/2 becomes -2/3) and then we change the sign (-2/3 becomes 2/3)
If -15 is equal to -0.2x, then 15/0.2=75
x=75
