A.) -540
Sum = N (first number + last number) / 2
N = count of consecutive numbers. Had the numbers included 1, then, N would have been 33. Since its range is 7 - 33 then 33 - 7 + 1= 27.
N = 27
Sum = 27 (-33 - 7) / 2
sum = 27 (-40)/2
sum = -1080 / 2
sum = -540
Answer:
y = 10x-37
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 10x+b
Substitute the point into the equation
3 = 10*4+b
3 = 40+b
Subtract 40
3-40 = 40+b-40
-37 = b
y = 10x-37
