Concept Check Fill in each blank with the correct response 3. The point with coordinates (0, 0) is called the - of a rectangular coordinate system. 4. For any value of x, the point (x, 0) lies on the -axis. 5. To find the x-intercept of a line, we let equal 0 and solve for -; to find the y-intercept, we let - - equal 0 and solve for . 6. The equation = 4 has a borizontal line as its graph. (x or y) 7. To graph a straight line, we must find a minimum of - points. 8. The point (-, 4) is on the graph of 2x - 3y = 0.
