What is point slope form

• x-x₁=m(y-y₁)

• y=mx+b

• y-y₁=m(x-x₁)

• y₁-y=m(x₁-x)

Write the equation of the line in point-slope form and then slope intercept form using the given information
(1, 2) m=7

• y-1 = 7(x - 2)
  y=7x+1

• y - 2 = 7(x - 1)
  y=7x-5

• y - 2 = 7(x + 1)
  y=7x+5

• y - 7 = 2(x - 1)
  y=7x-13

For the equation
y - 3 = 2(x + 4),
