Question

This does not make sense, pleas help me

Answer 1

Y = x + 2
if x = -3 then y = -3 + 2 = -1 so it's (-3,-1)
if y = x + 2 reflected across x-axis then x will stay the same but y is opposite
rule: reflected over x-axis (x,y) --->(x, -y)

so (-3,-1) will be ((-3,1)

answer
y = 1 when x = -3 reflected across x-axis
