Answer:
C. y = ⁵/2x - 5
Step-by-step explanation:
The linear equation representing the information on the table can be expressed in the slope-intercept form as y = mx + b, where,
m = slope = change in y/change in x
b = y-intercept/initial value = the value of y when x is zero
✔️Find m using two pairs given, say (0, -5) and (2, 0):
slope (m) = (0 - (-5))/(2 - 0) = 5/2
m = ⁵/2
✔️Find b:
when x = 0, y = -5. Therefore, y-intercept, b, is -5
b = -5
✔️To write the equation, substitute m = ⁵/2 and b = -5 into y = mx + b
Thus:
y = ⁵/2x + (-5)
y = ⁵/2x - 5

Answer:
58%
Step-by-step explanation:
Let's say you started with 100 dollars. Then, the next year, since it decreased by 30%, you would now have 100 - 30 = 70 dollars. Then, you decrease by 40%, so now it is 70 - 28 = 42 dollars. So, the total percent decrease is 100-42 = 58 percent.
