A linear equation has the x multiplied by a number, while exponential function has the x as a power
Answer:
Step-by-step explanation:
lets pick 2 points on the line....(6,5) and (10,3)
slope = (y2 - y1) / (x2 - x1)
(6,5)....x1 = 6 and y1 = 5
(10,3)....x2 = 10 and y2 = 3
now we sub
slope = (3 - 5) / (10 - 6) = -2/4 = -1/2
now we use y = mx + b
slope(m) = -1/2
u can use either of ur points...I will use (6,5)...x = 6 and y = 5
now we sub and find b, the y int
5 = -1/2(6) + b
5 = -3 + b
5 + 3 = b
8 = b
so ur equation is : y = -1/2x + 8 <===
Answer:
-$15
Step-by-step explanation:
To find the average yearly change, divide -120 by 8, since it has decreased by $120 over 8 years.
-120/8
= -15
So, the average yearly change in the value of the card is -$15
The answer would be 10.5 in decimal form. In fraction form you could reduce 6 and 4 and make the six a 3 and make the four a 2. Then multiply it out. Which would be 3/1 multiplied by 7/2 = 21/2
