Answer:

y + 3 = 4(x + 1)

Step-by-step explanation:

  • Point slope form: y - y1 = m(x - x1)
  • GIVEN: In this case, (x1, y1) = (-1, -3) and m = 4

When you plug this information into the formula, it becomes:

  • y -(-3) = 4(x -(-1))

This means that 1 and 3 are added to x or y because the equation has double negatives. Double negatives make a positive.

  • Therefore, y -(-3) = 4(x -(-1)) becomes y + 3 = 4(x + 1)
