Question 268394
General equation of a line is given by y=mx+c where m is the slope of the line and c is the y intercept (the y co-ordinate when x is zero).  
When m>0, it indicates that value of y increases as x is increased. 
when m<0, it indicates that value of y decreases as x is increased. 
when m=0, it means y is constant (line is parallel to x axis).
