Write an equation of the line in slope-intercept form.18. recall that 0°c = 32°f and 100°c = 212°f. a. using x for degrees celsius and y for degrees fahrenheit, findan equation of the line passing through (0, 32) and (100, 212).b. what is the slope of the line? explain what the slope means interms of degrees celsius and degrees fahrenheit. c. what is the y-intercept of the line? explain what the y-interceptmeans in terms of degrees celsius and degrees fahrenheit.
