Question 205326
Without graphing, identify the slope and the y-intercept for the line associated with the equation.
5x+20y=60 
Is the slope -5?
Thanks for your time and your help.

You have to solve it for y to get it in

slope-intercept form, which is {{{y=mx+b}}}

==========================================

{{{5x+20y=60}}}

Add {{{-5x}}} to both sides

{{{20y=-5x+60}}}

Divide every term by {{{20}}}

{{{(20/20)y=(-5/20)x+(60/20)}}}

Simplify:

{{{y=(-1/4)x+3}}}

Compare that to

{{{y=mx+b}}}

and equate like parts:

{{{m = -1/4}}}, that's the slope

{{{b=3}}}

which means that the y-intercept is the point (0,3)
