Question

The table below shows a relationship between x and y.

x y
-1 6
2 0
5 - 6
8 -12

Write an equation to represent the function relationship presented in the table.

Answer 1

find the slope between any two points

Answer 2

them use point slope form
y-y1=m(x-x1)

where (x1,y1) is any point given to you

Answer 3

slope = (y2-y1) / (x2-x1)

so from given table consider any point as x1 & y1 and next point is x2 & y2..

substitute the value and get m...

Answer 4

x y
-1 6
2 0
5 - 6
8 -12


m = (0-6)/ (2-(-1)) = -6/3 = -2...

Answer 5

just write the equation of the line using two pairs of point you'll get the relation ... (y-y1)=(y2-y1)/(x2-x1)* (x-x1)

Answer 6

i got the same answer as Ganpat

Answer 7

It's a good thing this is a linear relationship :)
