You need to come up with an array of answers for x and y that will be greater than 0.
x+4y>0. example if x is -1 and y is 1 will this be correct.
-1+(4*1)>0, -1+4>0. 3>0? Yes
if x is 1 and y is -1 then the equation becomes 1+(-4)>0 -3 is not>0 so it's not in the array
x could be -3 and y 1
You will plot a line to show all the answers.

Answer:
Slope: -3
Y intercept: (0, 9)
X intercept: (3, 0)
Step-by-step explanation:
In the equation y = mx + b, m is the slope and b is the y intercept.
Since the equation is y = -3x + 9, m is -3 and 9 is the y intercept.
So, the slope is -3 and the y intercept is at (0, 9)
To find the x intercept, plug in 0 as y and solve for x:
y = -3x + 9
0 = -3x + 9
-9 = -3x
3 = x
So, the x intercept is at (3, 0)
Total surface area = lateral area of cone + lateral area of cylinder + area of base of cylinder:
cone: πrL = π(5cm)(13cm) = 65πcm²
cylinder: 2πrh = 2π(5cm)(12cm) = 120πcm²
base: πr² = π(5cm)² = 25πcm²
total surface area = 65πcm² + 120πcm² + 25πcm² = 210πcm²
<h3>Simplifying
</h3>
5.5 + -1x = -4.5 + -1x
<h3>
Add 'x' to each side of the equation.
</h3>
5.5 + -1x + x = -4.5 + -1x + x
<h3>
Combine like terms: </h3>
-1x + x = 0
5.5 + 0 = -4.5 + -1x + x
5.5 = -4.5 + -1x + x
<h3>
Combine like terms:</h3>
-1x + x = 0
5.5 = -4.5 + 0
5.5 = -4.5
<h3>
Solving:
</h3>
5.5 = -4.5
<h3>
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</h3><h3 />
Hope this helps!
