Answer:
Third option) y = -2/3x + 2
Step-by-step explanation:
It is parallel to 2x + 3y = 12
4,4,4,5,5,5,6,6,7,8,8,8,9,10,10,10,10
It is the number 7.
Answer:
10/3
Step-by-step explanation:
(-2, 6) & (-5, -4)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - 6) / (-5 - (-2))
Simplify the parentheses.
= (-4 - 6) / (-5 + 2)
= - 10 / -3
Simplify the fraction.
-10/-3
= 10/3
This is your slope.
Hope this helps!
By Pythagoras Theorem,
the length of the other leg= (12^2-9^2)^1/2
