how do you write the standard form of an equation of a line that passes through the point (-4, -5) and is parallel to the line 2x-4y=5?

y=mx+c is the standard form where m is the gradient and c the intercept.
m=0.5 from the parallel
-5=0.5 times -4 + c (from -4,-5)
whence c= -3

the equation is y=0.5x - 3
