HELP find the equation of the trend line, show your work

Answer 1

Equation : y = 50x + 100

Explanation:

to find equation:

first take two coordinates: ( 10 , 600 ) , ( 14 , 800 )

now find the slope:
`(y2-y1)/(x2-x1)`

:
`(800-600)/(14-10)`

:
`(200)/(4)`

: 50

now find equation using: y - y1 = m( x - x1 )

: y - 600 = 50( x - 10 )

: y = 50x - 500 + 600

: y = 50x + 100
