Answer:
parallel lines
Step-by-step explanation:
you can substitute 2 x values and 2 y values from each equation into the gradient formula. for example, we can use 2 and 4 as our x values.
so:
y=3(4). (1)
y=12
y=3(2). (2)
y=6
so y2-y1/x2-x1
6-12/2-4
-6/-2
=3 (gradient)
y=3(4)-3. (1)
y=9
y=3(2)-3. (2)
y=3
y2-y1/x2-x1
3-9/2-4
-6/-2
=3 (gradient)
