Answer:
Slope = 0
Explanation:
y = 2 + 5 is simplified to y = 7
Because no matter the x value y will equal 7 the slope neither increases nor decreases, this means that the slope is 0.
However if you meant y = 2x + 5 the slope is the 2 because from each point it rises two units and runs to the right one unit to get the to next point.
Hope this helps,
