Answer:
y = 
x + 1
Step-by-step explanation:
Slope is rise over run, or the vertical progression over the horizontal progression.
Your example has a line that heads downwards, so we know that the slope is negative. If we count the squares, the "rise" is down by 4. We count the squares going horizontally and there are 5. So, your slope is .
The other half of the equation is the y-intercept, or where the line crosses the y axis. It appears to be at (0 , 1), so we can say that your y-intercept is 1.
A) x^2 + y^2 = 80
B) x * y = 12
What is x^2 -y^2?
B) x * y = 12
So y = 12 / x
A) x^2 + (12/x)^2 = 80
x^2 + (12/x)^2 = 80
x^2 + (144/x^2) = 80
Multiplying each side by x^2
x^4 + 144 = 80x^2
x^4 -80x^2 + 144 = 0

Answer:
r = 6 ft
Step-by-step explanation:
You would need 3622 ft to cover the outside. There’s no price per square foot of siding (or it’s not shown) so there’s no way to find it.
