Answer:
C
Explanation:
In y = mx+c, m is the gradient, c is the y-intercept.
Straight away we know that C is the correct answer since it intercepts the y-axis at -2. To make sure though, we can put random values into x and see if it works.
for x=1
y=1/3 (1) -2
y=-1 and 2/3
Since that is true in C we can put that as the answer.
