Answer:
y = x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = , hence
y = x + c ← is the partial equation
to find c substitute (4, 9) into the partial equation
9 = 2 + c ⇒ c = 9 - 2 = 7
y = x + 7 ← equation in slope-intercept form
Answer:
b. both functions have a negative slope
Step-by-step explanation:
The given function is
This function is of the form , where
is the slope and
is the y-intercept.
We can also determine the slope of the function in the table using any two points, say .
The slope formula is given by,
.
If , then,
.
We can see that both functions have a negative slope.
The correct answer is B.
