Life expectancy, according to certain actuarial analyses, can be calculated according to the following equations:
Men: 7.8 T - 59 L + 3842 = 0
Women: 6.2 T - 43L + 3279 = 0
1.) Do these equations demonstrate a linear relationship between time and life expectancy? Verify mathematically. Solve for L, then substitute function names M (x) and W (x) for L in each equation, rewriting the equations so they can be graphed. Graph these equations. ( This requires 1 correctly labeled graph of both equations or 2 correctly labeled graphs if you choose to graph them separately.) What do the slope and the y - intercept mean in the context of this problem?
