We have that the initial value of the function is the value at x=0; this is equal to 9. It shows the initial distance from the hole, when no time has passed (x=0). This is so because y has the units of distance. THe slope of the line is the quantity that shows the rate of change, namely how much a change in x is converted to a change in y. This is so because the slope has the units of y/x, namely distance over time (so it shows speed). Correct is b.
X = 213.075 First you have to get rid of the 4 and since it’s multiplying you to the opposite and that’s dividing. -3.7 divided by 4 = -0.925 X - 214 = -0. 925 Then you add 214 to -0.925 and get 213.075
A. because is $6 for every month as said in 6x, then an additional 12 for signing up, making 6x + 12 and she wants it to be under $60 so you use the less than sign making 6x+12 <60
