Answer:
y = 7/2 x -2
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-2 -5)/(0-2)
=-7/-2
= 7/2
We know the y intercept is -2 ( The x coordinate is 0)
Using the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = 7/2 x -2
Answer:
Sol1 you can use "first(first+last)/2" is 138(138+1)/2 - 38(38+1)/2 = 8850
Sol2 or you can look this 39+40+41+....+100+(100+1)+(100+2)+....+(100+38) = 1+2+3+.....+99+100+100(38) = 5050+3800 =8850
