Answer:
gradient = -

Explanation:
Parallel lines have equal slopes/ gradients
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4y + 6x = 8 ( subtract 6x from both sides )
4y = - 6x + 8 ( divide terms by 4 )
y = -
x +

y = -
x + 2 ← in slope- intercept form
with slope / gradient = -

The gradient of a parallel line is then m = -
