Answer:

 ∠b = 88 - 5x

Step-by-step explanation:

If a and b are complementary, then sum of two angles is 90

∠a + ∠b = 90

5x + 2 + ∠b = 90

             ∠b = 90 - 5x - 2

             ∠b = 88 - 5x

Slope is undefined and y int does not exist

Step-by-step explanation:

x=10 means it will be a vertical line where x= 10 so the slope is undefined and since it is perfectly vertical, it will never touch the y axis.
