Answer
x-intercept = -4 and y-intercept = 6
When x-intercept = -4; corresponding point on the x-axis = (-4, 0)
When y-intercept = 6; corresponding point on the y-axis = (0, 6).
By point-slope form,
⇒ y - y1 = m(x - x1)
⇒ y - 0 = [x - (-4)]
⇒ y = (x + 4)
⇒ 2y = 3x + 12
⇒ 2y - 3x = 12
⇒ 2y = 3x + 12
Hence, equation of line is 2y = 3x + 12.
