Mathematics: what is the cordinate?

Question

     a line with a slope of 1/5 crosses through points (6,3), if the abscissa of a point on the line is 11. What is the cordinate?  

 

 

Answer 1

slope of the line m = (y₂-y₁)/(x₂-x₁)

Abscissa of a point on the line x=11

Replace y₂ = y, y₁ = 3, x₂ = 11,m=1/5 and x₁ = 6 in the slope formula

1/5 = (y -3) / (11 - 6)

1/5 = (y -3) / 5

y-3=1

y=4

Cordinate is 4
