Question

Without graphing, identify the slope and the y-intercept for the

line associated with each equation or table of values
5x + 20y = 60

Answer 1

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
