write the slopeintercept form of an equation for a line that passes through A(3,4)and is perpendicular to the line that passes through e(4,1) and F(2,4)

The line you want to be perpendicular to has slope (41)/(2 4) = 1/2
That means the line you want to draw has slope m = 2. (The product of the two slopes must be 1)
Your equation will be y = 2x + b, where
4 = 2*3 + b
b = 2
y = 2x  2 is the equation.
