Answer:
Step-by-step explanation:
The equation of a line in point-slope form is
where y1 and x1 are 2 known points, and m is the slope of the line. So simply just fill in the blanks.
y is a variable so it is left alone (since there is no subscript).
y1 we are told is 1.
m we are told is -3 (the slope)
x is a variable so it is left alone (since there is no subscript).
x1 we are told is 6.
Step-by-step explanation: if its asking how much money he spends in total you multiply
$3.25 x 5 = 16.25
The principal decreases by
22275 -18900 = 3375
in those 9 months, so the average monthly principal payment is
3375/9 = 375
Her average payment rate on the principal during this time is $375 per month.
