And has diameter 10 v2 Units. 12. (i) Show that the points (4,3), (2,0) and (-4, - 9) are collinear.(ii) Show that the points (-1, -1), (2, 3) and (8, 11) are collinear |

Answer» -STEP explanation:if Slope of AB is equal to slope of BC then A, B, Care COLLINEAR A=(4,3),B=(2,0) and C=(-4, - 9)slope of AB = difference of y COORDINATES/ difference of X coordinates =(3-0)/(4-2)=3/2------->Islope of BC = difference of y coordinates/ difference ofX coordinates==(-9-0)/(-4-2)=-9/-6=3/2----->IIfrom I and IIA, B, C, are collinear |
