Answer:
y = -2.5x + 4
Step-by-step explanation:
Slope intercept form: y = mx + b
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 5x from both sides.
5x (-5x) + 2y = 8 (-5x)
2y = 8 - 5x
Next, divide 2 from both sides to isolate the y.
(2y)/2 = (8 - 5x)/2
y = (-5/2)x + (8/2)
y = -2.5x + 4
y = -2.5x + 4 is your answer.

81.5-4.5 will equal your answer!
this is because x and 4.5 would equal 81.5, meaning if you subtract— you’ll get your X
The formula is
A=p (1+r)^t
A people after 4.5 years 15000
P current people ?
R rate of growth 0.065
T time 4.5 years
Solve the formula for p to get
P=A÷(1+r)^t
P=15,000÷(1+0.065)^(4.5)
P=11,298.42 round your answer to get 11298
Hope it helps!
