Equation - F(x)= -x+5
Use the formula
y2-y1 5-1 4
--------- --------- ------ M = -1
X2-x1 0-4 -4


than Calculate the y-axis intercept(B) by using f(x)=mx+b
Insert -1 for m, 4 for x and 1 for f(x).

1=-1*4+1*b | Swap both sides of the equation.
1*b+-4=1 | +4
1*b=5

So, the y-axis intercept is at 5
Therefore, the equation of the function is f(x)=-x+5

First, subtract to get the difference.
2.85 – 2.78 = 0.07

Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).

Hope this helps!
