Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.
Answer:
y= 2/5-1
Step-by-step explanation:
You get the 2/5 because you go 2 to the right and go 5 up, the -1 is because the x-int is at -1.
Find the area of the circle
A of circle = πr²
radius = diameter/2 = 48/2 = 24
Area = (3.14)(24)²
Area = 1808.64 in²
Hope this helps :)
