Which of the following points lies on the line 3x – 8y = 11?
- (1, 1)
-
(1, -1)
- (-1, 1)
- (-1, -1)
The correct answer is: B
Explanation
If a point lies on a particular line. It will satisfy the equation of the line.
Test the points given in the options any that satisfy the equation of the line, is the point.
Thus, the point(1, -1) lies on the line 3x - 8y = 11
That is, putting x = 1 and y = -1 into 3x - 8y to see if the result will equal 11
3(1) - 8(-1) = 11.
