Answer:
Any line with the slope of 4/3 would be perpendicular.
Step-by-step explanation:
To find this, first solve the equation for y.
3x + 4y = 7
4y = -3x + 7
y = -3/4x + 7/4
Perpendicular lines always have opposite and reciprocal slopes. Therefore, we flip the slope in the original equation (-3/4 becomes -4/3) and then we change the sign (-4/3 becomes 4/3)
