c), etc., is the locus represented bythis equation. Another equation as 4>x + 3y = 8 has also an infinitenumber of solutions, and if these two equations aresolved together, the common solution obtained, in thiscase x = —1, y = i, gives the coordinates of the pointof intersection of the loci… … Fig. 16. (Unit = & Inch.) paper, we see that the loci appear to be st. lineswhich intersect at the point (d) ( — 1, 4). 24.—Exercises X. Plot the following loci on squared paper and find thecoordinates of their points of intersection:— tyrf 4a; - y >= 1 and x - 2y = - 12 (b) x + 2y = 7 and…
