To write the rule or equation of the linear function we need to find the slope of the function first. Using any two points we can find the slope.
Using the first two points (-3, -1) and (0, 2).
Slope (m) of the function would be:

Using slope and the point (0,2) we can write the equation of the line as:
y - 2 = 1(x-0)
y = x + 2
Thus, the correct rule for the given linear function is x+2
9,500 just add the 0 always add 0 if you multiply by 10. 00 for 100 and 000 for 1000
5 because it is equal to the length of the sides
6* 25 = 150 = (6*20= 120) + (6*5=30) Then Add 120+30= 150 so your answer is 5
24.5% are buses:
98/400=0.245
you multiply that by 10 to get the percentage.
