This is a calculus worksheet

1. Classify thes equations in R' as lines (L) or planes (P), then state its form? x= a) y=9-1 = = 6+0.51 b) = + s +t C) x=7 2. Determine the equation of the line that passes through the y-intercept of the the plane 2x + 3y - z = 6 and the point (-2, 1, 3). Express the line in symmetric form. 3. Determine the scalar equation of the plane formed by the the lines = + t & x = 4s - 2, y = 2s, z = 3 - 2s. 4. Determine the area of the triangle formed by the x, y and z-intercepts of the plane 2x - 3y + 5z = 60
