Linear equations are equations that have constant slopes
The ordered pairs of the equations are:
(0,9), (0,-6), (0,-1) and (0,-1)
How to determine the lines
The equations are given as:
y=-2x+9
y=-2x-6
y=3x-1
y=1/2x-1
Set x to 0, to calculate the corresponding y-value in all the equations
[tex]y=-2(0)+9 =9[/tex]
[tex]y=-2(0)-6 = -6[/tex]
[tex]y=3(0)-1 =-1[/tex]
[tex]y=1/2(0)-1 = -1[/tex]
So, the ordered pairs of the equations are:
(0,9), (0,-6), (0,-1) and (0,-1)
