John reads an equal number of pages of a book every week. the graph below shows the number of pages of the book left to read, y, after x weeks:
which equation best models the relationship between x and y?
y = −5x + 25
y = −25x + 125
y = −25x + 175
y = −5x + 125

If angle 2=3x +1 and angle 3=2x +4what is angle 2

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.

What would the rule be for the reflection of y=-3
