For temperature-dependent ohmic resistors (at least the kind we're focusing on), the relationship between resistance & temperature is linear. With that in mind, compare the formula for temperature-dependent ohmic resistance to the equation for a line (y = mx + b) and determine the slope and the y-intercept for a graph of R vs. T. Your answers should be in terms of Ro, ?, & To. [NOTE: for Ro & To the subscript is a lowercase o] R = Ro[1 + ?(T − To)] slope = y-intercept =
