Are the lines x− 2y= 4 and y= 2x − 2 parallel, perpendicular, or neither? Explain your answer.

For lines to be parallel, the slope has to be the same.

For lines to be perpendicular, the slope has to be the negative reciprocal.  4 x + 2 y = 7

2 y = − 4 x + 7

y = − 2 x + 7 /2

Compared to : y = 2 x − 3

Step-by-step explanation: Just a good guess.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
