Problem 240

Problem 240

Without graphing, identify the slope and the y-intercept for the line associated with each equation

 

Solution

 

5x+20y=60

we can write it as

20y=-5x+60

y=-  + 3

we know the standard form of line is

y=mx+c

here m=slope

and c is y intercept

compair the given equation by main equation of line

so slope= –

and y intercept is 3
