Explanation:
Set up two equations
2
x
+
2
y
=
54
x
×
y
=
176
Solving the first equation for x

Divide both sides by 2
(

y
=

Apologies if it’s dark but here’s the work for your question. If you need an explanation, let me know.
Answer:
The equation would be y = -1/2x + 5
Step-by-step explanation:
To find the equation, we first need to use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 0)/(0 - 10)
m = 5/-10
m = -1/2
Now that we have that, we can use that and a point to find the full equation.
y - y1 = m(x - x1)
y - 0 = -1/2(x - 10)
y = -1/2x + 5
