Astudent is attempting to convert a slope-intercept equation into standard form. which of the following statements best applies to the sample math given below? given y=-2/3x-1/2, i first isolate the constant. after doing so, i get the equation 2/3x+y=-1/2. since 2/3 is positive, the equation 2/3x+y=-1/2 is the standard form equivalent of the slope-intercept equation given. a. the work shown to isolate the constant is not correct b. the student omitted work to change the sign of one or more terms c. the final answer is not in standard form d. the work shown is correct
