Two lines that intersect at 90 degrees are considered perpendicular to each other.
Answer:
see explanation
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
The answer is 43 when you add 29 back to 57 then divide by 2
