Answer 3

umm its asking for a equation

Answer 4

8x%2B9y=11 Start with the given equation.


9y=11-8x Subtract 8x from both sides.


9y=-8x%2B11 Rearrange the terms.


y=%28-8x%2B11%29%2F%289%29 Divide both sides by 9 to isolate y.


y=%28%28-8%29%2F%289%29%29x%2B%2811%29%2F%289%29 Break up the fraction.


y=-%288%2F9%29x%2B11%2F9 Reduce.





In order to graph the equation y=-%288%2F9%29x%2B11%2F9, we only need two points to create a straight line




--------------------------------Let's find the first point--------------------------------

y=-%288%2F9%29x%2B11%2F9 Start with the given equation


y=-%288%2F9%29%287%29%2B11%2F9 Plug in x=7


y=-56%2F9%2B11%2F9 Multiply -8%2F9 and 7 to get -56%2F9


y=-45%2F9 Add


y=-5 Reduce
