Graphing

Without graphing, identify the slope and the yintercept for the
line associated with each equation or table of values
5x + 20y = 60

A straight line of the form y=mx+c has slope m and y intercpet of c.
So we need to rearrange the equation into this form
20y=5x+60
so
y=(5x/20)+ 60/20
y=0.25x+3
thus m=0.25 and c=3
