Finding Equations of Lines

Write the equation of the line in gradient-intercept form.

Write an equation of the line in point-gradient form containing (-1,1) and (4,-9).

• y +1 = - 2(x - 1)

• y = -2x - 1

• y - 1 = - 2(x + 1)

• 2x + y = -1

Which of the following is the gradient-intercept form?

• y = mx + b
