1. the first method that you will need to create is to calculate the y value of a line, given by the slope(m), the x value (x) and the y intercept (b). your method should be named linevaluefory with a return type of double. y. your method should accept 3 parameters, all of type double. the first parameter will be the slope of the line (name this parameter m), the second parameter should be the x value (name this parameter x) and the last parameter should be the y intercept (name this parameter b). the formula to calculate the y value is y
