Answer :
The point slope form equation is
Y - y1 = m ( X - x1 )
Then replace values m= 2/7. And point (-7,7)
Y - 7 = (2/7)•( X - (-7)) = (2/7)• ( X + 7)
Y = (2/7)•X + 7 + (2/7)•7 = (2/7)X + 2 + 7
Y = (2/7)•X + 9
The point slope form equation is
Y - y1 = m ( X - x1 )
Then replace values m= 2/7. And point (-7,7)
Y - 7 = (2/7)•( X - (-7)) = (2/7)• ( X + 7)
Y = (2/7)•X + 7 + (2/7)•7 = (2/7)X + 2 + 7
Y = (2/7)•X + 9
