1. (3 marks) a) Find the slope and the y-intercept of the line with the given equation and sketch the graph using the slope and the y-intercept. 24x + 40y= 15 Find the x-intercept and the y-intercept of the line with the given equation. Sketch the line using the intercepts. b) 4x-3y = 12 2. a) Chains support a crate, as shown in Fig. 5.20. The equations relat- ing tensions T and 72 are given below. Determine the tensions to the nearest 1 N from the graph. 0.87 - 0.672 = 12 T T 12 N 0.67] + 0.872 = 68 68 N Fig. 5.20 (5 marks) 1.
