Answer:
1). Other line is, y =
2). Solution of the system is (3, 6)
Step-by-step explanation:
From the table (1),
Let the equation of the line from the given table is,
y - y' = m(x - x')
Where m = slope of the line
(x', y') is a point lying on the line.
Choose two points from the table which lie on the line.
Let the points are (0, 5) and (3, 6)
Slope = m =
=
=
Therefore, equation of the will be,
y - 5 =
y = -------(1)
Let the other line from the table (2) is,
y - y" = m'(x - x")
Two points taken from this table are (0, 7) and (3, 6)
m' =
=
Equation of the line will be,
y - 7 =
y = -------(2)
Therefore, equation of the other line will be, y =
By adding equations (1) and (2),
y + y =
2y = 12
y = 6
From equation (1),
6 =
x = 3
Therefore, solution of the system is (3, 6).
