Which of the given points belongs to the straight line 5x-7y = 0? a) (1; -1); b) (-1; 1); c) (2; 2); d) (4; 1)

The coordinates of the points are given.

a) (1; – 1); b) (- 1; 1); c) (2; 2); d) (4; 1)

To solve this problem, we need to substitute the values of all points into the expression 5x-7y = 0. For clarity, we transfer the value from the variable y to the right side of the expression.

5x = 7y

Now we substitute the values of all points.

5 * 1 = 7 * (- 1). The expression is false.

5 * (- 1) = 7 * 1. The expression is false.

5 * 2 = 7 * 2. The expression is false.

5 * 4 = 7 * 1. The expression is false.

None of the given points belongs to the specified straight line.
