Use the formula,

I = Prt

P = Principal amount = 400

I = interest = 18

r = annual rate

t = time in years = 9/12 = 3/4

so,

18 = 400*r*3/4

r = 0.06

so the annual interest rate is 0.06 or 6%

Y=2x+5 is greater than the rate of change of the function represented in the graph. To find this, first remember that rate of change is just slope. This means that you can easily find the slope of the already given function y=2x+5, which is just 2. Then you take two pairs from your table. I took -1,0 and 2,3. You then place those into the equation used to find slope, y2-y1 over x2-x1. 3-0 equals 3 and 2-(-1), which means 2+1, since you’re subtraction a negative number is also 3, meaning your slope or rate of change is 1. 1 is a smaller number than 2 and therefore the rate of change in the already given function is greater than that of the table. Hope this helps!
