text: what is the answer and how do you do it? find the slope of the line that is the graph of the equation 5x - 3y = 30.  a.3/5   b.5/3   c.-3/5   d.-5/3   e.5 change the equation into the form:     y = mx + b        [m represents the slope of the line]    [b represents the "y-intercept"]  so:     5x - 3y = 30       - 3y = 30 - 5x         3y = -30 + 5x         3y =  5x - 30          y =  5/3 x -10  now we know the slope is m=5/3 and the "y-intercept" is  b=-10.  so the answer is b, slope = 5/3.
