Question

Which lines are parallel to 8x + 2y = 7?

Answer 1

Answer: y = -4x+b

Step-by-step explanation: All lines with slope -4 are parallel to this line. For example: y=-4x

Answer 2

8x + 2y = 7

2y = -8x + 7

y = -4x + 7/2; this line has slope equal -4

Parallel lines, slope is the same so slope of parallel line is also -4

A. y − 1 = 4(x + 8); slope m = 4....FALSE

B. y = −4x + 15; slope m = - 4....TRUE

C. 16x + 4y = 9; 4y = -16x + 9 so y = -4x + 9/4; slope m = - 4....TRUE

D. y = −4x; slope m = - 4....TRUE
