All you need to do is add 37+16 and it will be equivalent to 53
Explanation:
Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.
The actual slope is ...
slope = Δy/Δx = 6/2 = 3
<span>2x - 3(-4x + 2 )
2x+12x-6
14x-6
2(7x-3)</span>
The easiest way to do this is to multiple 7 and 3, which gives you 21. Julie will spend $21 on the gifts.
