S.2 REVION QUESTIONS 1; Find the equation of a line that passes through the points (-4,6) and (2,4) Given that a line passes through the points (6,1) and has a gradient 4 find the equation of the line. Find the equation of a line that is perpendicular to another line y = 3x and passes through the point (-3, -2) Find the equation of a line which passes through the point (3,7) and is parallel to the line 2y = 4 + 3x Using a pair of compasses a ruler and a pencil only dray a triangle whose sides are AB = 8cm, BC = 6 cm and AC = 7cm. Hence draw a circumscribing and find its area. Solve the following simultaneous equations. y = 2x + 6 4x – 3y = 4 x – y = 4 2x + 8 = -1 3 – 4x =2y x + y = 5 The table below shows the marks scored by S.3 students in a mathematics test. 60 68 67 67 68 64 65 61 60 50 68 64 67 65 63 65 64 67 68 65 62 61 60 67 67 68 67 67 67 64 61 60 69 68 65 67 Draw a distribution table and use it to; Find the mean Estimate the mode and median Solve – = 6 Kato went to a shop to buy a radio and was given a 12%discount. If the radio was priced at She 45000, how much did he pay. An agent sold 100 dosens of picfare exercise books at Shs 3000 a dozen. If he receives a commission os 4% for the sales worth Shs 200000 work and 5%for the, how much commission does he get.
