Find an equation of the line where the planes Q and R intersect. Q: - 2x + 3y - 4z = 1; R: x+y+z= −1 Choose the correct answer below. 1 O A. An equation of the line is given by x= -5t, y=-- 5 5 4 O B. An equation of the line is given by x= - +7t, y = −5+ 3t, z = -2t, where - ∞ <t<∞. 4 +7t, z= 5 O C. An equation of the line is given by x = −5+ 3t, y = − 2t, z = -- 4 O D. An equation of the line is given by x = - 5 - 4 - 2t, where - ∞ <t<∞o. 5 1 +7t, y = -5 - 4t, where - ∞ <t<∞. -2t, z = -5t, where - ∞ <t<∞.
