The slope of 4x-2y+7=0 is 2.

Therefore, the perpendicular to this line has a slope -1/2.

The y-intercept 2x+3y-10=0

is 10/3.

Therefore, the line passes through (0, 10/3)

The equation of the line would be

y - 10/3 = -1/2(x - 0) = -x/2

2y - 20/3 = -x

x + 2y - 20/3 = 0

3x + 6y - 20 = 0 is the required equation.
