What's the slope-intercept equation of line which is parallel to y = 2/5x-3 and passes through point (0,5)
A. y = -5/2x - 3
B. y = -5/2x + 5
C. y = 2/5x + 3
D. y = 2/5x + 5
Its D, but how do u figure that out? please explain step by step.

y = 2/5x - 3
parallel lines have equal slopes
slope intercept form of an equation
y = mx + b
m = slope, b = y-intercept
parallel to y = 2/5x - 3,
and through P(0, 5)
m = 2/5
y intercept = 5
so, the equation would be
D. y = 2/5x + 5
