Two lines represented by the equations \(y=x+1\) and \(y=2x+3\) intersect at point P. What are the coordinates of P?
(–2, –1)
(–1, 2)
(1, –2)
(2, –1)
(1, 2)
To find the coordinates of point \(P (x, y)\), equate \(y\) or \(x\) of both the equations;
\(x + 1 = 2x + 3\)
\(x = -2\)
So, \(P = (-2, y)\)
Only one option has a x-coordinate to -2
Hence, option A
