When the graph has a reflection on the y-axis, the equation of the reflected graph is given by y = f(–x).
So, the equation of the reflected graph is
y = –2x – 5
So, the slope is –2.
This line passes through (0, –5) and (4, 3) The slope m = 3+5 = 3+5 = 2
and the y-intercept of the line is –5 So, the equation of the line is
y = mx + c
y = 2x – 5
