Step-by-step explanation:
To find the intercepts, that is where the graph crosses the x and y axes.
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x-intercept
x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept
y = 0 : 8x + 0 = - 9 ⇒ x = -  ⇒ ( -
 ⇒ ( -  , 0) ← x- intercept
, 0) ← x- intercept
 
        
             
        
        
        
Answer:
∠ DBE = 25.5°
Step-by-step explanation:
Given ∠ DBC = 90° and ∠ DBE + ∠ EBC = ∠ DBC, then
∠ DBE = ∠ DBC - ∠ EBC = 90° - 64.5° = 25.5°
