Step-by-step explanation:
What is the meaning of the y-intercept of the linear model?
a) The initial value of the car is 14,000.
b) The average value of the car is 14,000.
c) The car’s value decreases by $875 each year after it was purchased.
d) The car’s value decreases by $16 each year after it was purchased.
Please help.
Answer:
Option a) The initial value of the car is 14,000
Step-by-step explanation:
we know that
The linear equation into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
Remember that
The y-intercept is the value of y when the value of x is equal to zero
In this problem we have
so
The slope is equal to
The y-intercept is
therefore
is the value of the car for x=0 (initial value)
O . F'(x) = 2 - x
O B. f'(x) = x-2
O c. f'(x) = 2x
OD. F'(x) = x+2
Answer:
D
Step-by-step explanation:
let y = x - 2 and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
now change x to (x) and y back to x, thus
(x) = x + 2 → D
Slope is already given in the question so we only need to solve for the y-intercept.
Slope intercept form: y = mx + b
m = slope
b = y-intercept
-3/5 = -0.6
1 = -0.6(1) + b
1 = -0.6 + b
1 + 0.6 = -0.6 + b + 0.6
1.6 = b
Now, write in slope-intercept form.
y = -3/5x - 1.6
