Question

Find an equation for the line with slope m =2/7and which goes through the point ( - 7,7).

Answer 1

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
