Answer:
C.
Step-by-step explanation:
When you write the equation of a line in slope-intercept form,
y = mx + b,
m is the slope.
Parallel lines have equal slopes.
The given line is
y = (4/5)x - 1
and has slope 4/5.
The only equation in the choices with slope 4/5 is in choice C whose line is
y = (4/5)x + 2.
