When we're finding the mean we add all the numbers then we DIVIDE THE AMOUNT OF NUMBERS. In this case, we have to divide by 5 because that's the amount of numbers there are.
Answer:
1
Step-by-step explanation:
False
lets say u have 2 sets of points (1,2) , (3,4)
now lets say (1,2) is (x1,y1) and (3,4) is (x2,y2)
slope = (y2 - y1) / (x2 - x1)
slope = (4-2) / (3-1) = 2/2 = 1
now, lets say (1,2) is (x2,y2) and (3,4) is (x1,y1)
slope = (y2 - y1) / (x2 - x1)
slope = (2 - 4) / (1 - 3) = -2/-2 = 1
in conclusion, the naming of the points will not effect the slope
Answer:
X=7/2 Y=1
Step-by-step explanation:
4X-Y=13
4X-13=Y
2X-3(4X-13)=4
2X-12X+39=4
-10X+39=4
-10X=4-39
-10X=-35
X=7/2(-35/10)
Y=4(7/2)-13
Y=14-13
Y=1
