slope

# = 4/5 #

#### Explanation:

the equation of a line in the form y = mx + c , where m , represents the gradient (slope) and c , the y-intercept , allows m and c to be extracted quite 'easily'.

rearrange 4x -5y = 20 into the form y = mx + c

hence 5y = 4x - 20

divide both sides by 5

# y = 4/5 x - 4 rArr m = 4/5 #
