Answer:
C: Either the mean or median; both are 5
Step-by-step explanation:
MEAN: 5+2+4+8+6= 25 = 25/5= MEAN IS 5
MEDIAN: put it in order: 2,4,5,6,8
cross out 2,8,4,6
left over number is 5
So median is 5
Answer:
1)9-7+x

Answer:
y= 6x-9
Step-by-step explanation:
1. First find the gradient between the two points. Gradient =6
2. Using the formula y= mx+c substitute the gradient into the equation. You'll get something like this: y= 6x+c
3. Substitute the point (4,15) into the equation. You'll get something like this: 15= 6(4) +c.
4. Calculate the value of c. You'll get - 9 as an answer to that.
5. Substitute the value of c into the original equation. Your final answer will be y= 6x-9
