Using the distance formula
d= square root of (x2-x1)^2+(y2-y1)^2
(9-9)^2+(10-3)^2
0^2+7^2
0+49
Square root of 49 is 7
d=7
Answer:
D) A graph shows both axes unnumbered. Points are scattered all over the graph.
Step-by-step explanation:
The value of "r" tells you how strong the correlation is between the independent and dependent variables. If its close to 0, then there will be hardly any correlation, so a good example of this is the 4th option where there's no pattern in the data set.
You require the Pythagorean Theorem: in a right triangle, the sum of the squares of the legs equals the square of the hypotenuse.In this case 6^2 + 8^2 = 36 + 64 = 100 = 10^2
the hypotenuse is 10.
Replace X in the equation with the values in the table and calculate:
2X-5:
2(-4) -5 = -8 -5 = -13
2(-2)-5 = -4-5 = -9
2(1)-5 = 2-5 = -3
2(3)-5 = 6-5 = 1
2(5)-5 = 10-5 = 5
