Answer:
slope = -2
y-intercept = 5
Step-by-step explanation:
1) Find slope:
=
= -2
-2 = slope
2) Find y intercept trough point slope and slope-intercept forms
y - y1 = m (x - x1)
y - 9 = -2 (x + 2)
y - 9 = -2x -4
+ 9 + 9
y = -2x + 5
y = mx + b with b being the y-intercept
5 = y-intercept
Answer:
B
Step-by-step explanation:
let f(x) = y and rearrange making x the subject
y = ( multiply both sides by 7 to clear the fraction )
7y = x + 2 ( subtract 2 from both sides )
7y - 2 = x
Change y back into terms of x with x the inverse function, that is
p(x) = 7x - 2
Answer:
$208.33
Step-by-step explanation:
Julie has to make the down payment which is 25% of $60000 after saving for 6 years.
Therefore, Julie has to save a total of dollars.
And Julie has to save it for the duration of 6 years i.e. (6 × 12) = 72 months.
Hence, Julie has to save dollars every month to make the down payment after 6 years. (Answer)
