Let and
. Now we evaluate the given function at
:
(1)
Which means that is less than the y-component of A. Therefore, the right answer is
.
Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m = =
= -
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2
Answer:
Inverse variation k=4
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
In this problem
The graph represent a inverse variation
Because
if x increases ----> y decreases
if x decreases ----> y increases
Find the value of k
we have that
For x=2, y=2 -----> see the graph
substitute
