Answer:
a. y = - x - 4
b. y = 8
Step-by-step explanation:
RULE :
reflecting a line of the linear equation ‘y = ax + b’ over the y-axis gives us
another line (image line) of equation ‘y = - ax + b’
………………………………………………………………………………
a.
Line : y = x - 4 after reflection becomes line : y = - x - 4
b.
Line : y = 8 after reflection becomes line : y = 8
