#(0,6)#

Explanation:

An ordered pair represents any point on a curve (straight line).

Let point 1 be #P_1->(x,y) = (0,y)# for equation #y=2x+6#

Then by substitution #color(brown)(P_1->y=2x+6)->color(blue)(y=2(0)+6)#

#=> P_1->(x,y)=(0,6)#

(0 ,6)

Explanation:

From the ordered pair (0 ,?) we are required to find the y-coordinate given that the x-coordinate = 0. Remember that the ordered pair is the coordinate point (x ,y)

To find y , given x , substitute the value of x into the equation which connects them.

x = 0 : y = 2(0) + 6 = 0 + 6 = 6

#rArr(0,?)=(0,6)#
