please show me step by step how to solve the following equation -2x+4y=9
to find the slope of the line.

  • pre algebra - ,

    Rearrange the equation so that it is in the y = mx + b form. The "m" will be the slope.

    -2x +4y = 9

    Add 2y to both sides.
    4y = 2x + 9

    Divide both sides by 4
    y = (1/2)x + 9/4

    The slope is 1/2
