Question 1086072
2x-4y = - 1
—

Solve for y:

-4y = -2x - 1
    y = (-2x - 1) / -4
    y = (1/2)x + (1/4)      (*)

This has form y = mx + b   
                       m = slope
                       b = y-intercept (where the line meets the y-axis)

 By comparing (*) to y = mx+b, we get slope = {{{highlight_green(1/2)}}}
