A: Zero
B: one
C: two
D: infinitely many

0

Step-by-step explanation:

12x+1=12x+3-2

12x+1=12x+1

12x-12x=1-1

0x=0

x=0×1

=0

y=1/3x+3

Step-by-step explanation:

the general equation for a straight line is y=mx+c.where c is the y cut therefore the y cut on our graph is at (0,3)therefore c is 3

we then find the gradient which is "m" on our equation using the formula m=y2-y1/x2-x1

then we substitute the m and c then tha is the equation.
