Question

Which of the following is a solution of the equation –5x + 2y = 14? (a) x = 5; y = 1 (b) x = 0; y = – 7 (c) x = –2; y = 2 (d) x = 1; y = – 3 4. The equation x = – 4 represents the line which : (a) is parallel to x-axis (b) passes through origin (c) is parallel to y-axis (c) is perpendicular to y-axis

Answer 1

Answer:

put all the values of x and y in the equation see if you get 14.

Ans is (c) put x=-2 and y=2 in the equation, you will get 14 = RHS

The equation x=-4 is a line parallel to Y axis at a distance of -4 from the origin
