Question 809509: Line with slope 1/5 passes through (6,3). If the ordinate of a point on the line is 4, what is its abscissa?
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! y - y1 = m(x - x1)
y - 3 = (1/5)(x - 6)
y - 3 = (1/5)x - (1/5)6
y = (1/5)x - 6/5 + 15/5
y = (1/5)x + 9/5
---
given (x,y)
x = abscissa
y = ordinate
---
4 = (1/5)x + 9/5
20/5 - 9/5 = (1/5)x
11/5 = (1/5)x

Answer:
x = 11
