1. The y-intercept of the line with equation 2x + 3y = 5 is 5/3. 2. To find the equation of a line, it is sufficient to know two points on the line. 3. The point P(1, 1) lies on the circle with radius 1 and center (1, 1). 4. A system of two linear equations has exactly one solution. 5. If three vertices of a parallelogram are (0, 0), (2, 0) and (5, 4), then the fourth vertex is (7, 4). 6. If three of the vertices of a rectangle are (-a, 0), (a, 0) and (-a, b), then the fourth vertex is (a,-b).
