question_answer 1)

Find the intercepts cut off by the plane 2x + y – z = 5. 

Answer:

Given equation of plane is 2x + y ? z = 5.           ? (1)       To find X-intercept, put y = 0, z = 0 in equation (1) we get     To find Y-intercept, put x = 0, z = 0 in equation (1), we get        0 + y ? 0 = 5  y = 5 -intercept = 5       To find Z-intercept, put x = 0, y = 0 in equation (1)       0 + 0 ? z = 5  z = ?5  Z-intercept = ?5
