Question

If the points (x,-2),(5,2),(8,8) are collinear, then x is equal to
​

Answer 1

Answer:

3

Step-by-step explanation:

a(x,-2),b(5,2),c(8,8)

as given points are collinear

Man=Mbc=Mca

2+2/5-x=8-2/8-5=8+2/8-x

taking 3+2/5 -x=8-2/8-5

4/5-x=6/3

x=3

Answer 2

Step-by-step explanation:

• Equating the slopes

• (2+2)÷(5-x) = (8-2)÷(8-5)

• 4/(5-x) = 6/3

• 5-x = 2

• x = 3

• This is my answer
