One. that is the definition of a line.
Through any two points, there is exactly one line.
Equation 1: x² + y = 7
Equation 2: 3x + 7 = 9
Use Equation 2 to solve for "x" and plug in "x" into Equation 1 to solve for "y".
3x + 7 = 9
3x = 2
x = 
*********************************
x² + y = 7
(
)² + y = 7
+ y = 7
y = 7 -
y =
