Nora observes that if f(x)=4−x, then the graphs of 14f(x) and f(x)−3 both have a y-intercept of 1.

Does this mean that multiplying f(x) by 14 and subtracting 3 from f(x) transform the graph in the same way? Math item stem image

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
