What is the point slope form of the line with slope 2/5 that passes through the point (-4, -7)?

y+7=2/5(x+4)
y-7=2/5(x-4)
y-4=2/5(x-7)
y+4=2/5(x+7)

Answer:

A. y + 7 = 2/5(x + 4)

Explanation:

  • gradient (m) = 2/5
  • (x1, y1) → (-4, - 7)
  • x1 = -4
  • y1 = -7

so,


\rm y - y1 = m(x - x1)


\rm y - ( - 7) = (2)/(5) (x - ( - 4))


\boxed{ \rm y + 7 = (2)/(5) (x + 4)}
