Question

find the slope of a line parallel to y= -2/5x + 4/5

Answer 1

If another line is to be parrallel, then that means it will have the same SLOPE as the line/equation you are given.

so, you have:
y= -2/5x + 4/5

the coefficient (or the number) that is right in front of the 'x' is the slope.
which is -2/5

the coefficient infront of the x, will always be the slope when the equation is in 'slop-intercept' form fyi ^_^
