Find an equation of the line that has slope m and yintercept
     Find an equation of the line that has slope m and y-intercept b  (1) m = 3, b = 4  (2) m = 0, b = 5 
  
  Solution
a) m = 3
b = 4
standard equation of line is y =mx + b
plugging the values in standard equation we get
y = 3x + 4
2) m = 0 , b = 5
plugging the values in standard equation we get
y = 0x + 5
y = 5
