Determine whether the lines, 2x – y = 7 and y = – 1/2x – 10 are parallel or perpendicular . Explain the reason for your answer.

perpendicular

Step-by-step explanation:

a line is perpendicular to another line when m of one line is the negative or opposite reciprocal of the other. m= 2

the perpendicular lines for that would be 1/2 which is the reciprocal and then the opposite sign which is negative.
