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

Answer:
Equation : y = 50x + 100
Step-by-step explanation:
to find equation:
first take two coordinates: ( 10 , 600 ) , ( 14 , 800 )
now find the slope: [tex]\frac{y2-y1}{x2-x1}[/tex]
: [tex]\frac{800-600}{14-10}[/tex]
: [tex]\frac{200}{4}[/tex]
: 50
now find equation using: y - y1 = m( x - x1 )
: y - 600 = 50( x - 10 )
: y = 50x - 500 + 600
: y = 50x + 100
