It looks like you will make a line going through the x axis on -19 because you move over your negative.
(1/2 + 1/3)^-2
(5/6)^-2
(6/5)^2
= 36/25
y = 20x
The graph passes through the origin , hence is of form
y = mx ( m is the slope )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (2, 40) and (x₂, y₂) = (4, 80) ← 2 points on the graph
m =
=
= 20
y = 20x
Answer:
Greetings! I have your answer, as I have done the test, was in fact correct.
Step-by-step explanation:
Angela’s age is 4 years more than twice Joe’s age:
2x + 4
Deshawn’s age is 3 years more than half Joe’s age:
I/2 + 3
Bruce’s age is 4 years more than half Joe’s age:
I/2 + 4
Callie’s age is 3 years less than 4 times Joe’s age:
4x + 3

I hope this helps! ^^
X - 4y....when x = -3 and y = 6
-3 - 4(6) =
-3 - 24 =
- 27 <==
