The table shows the values of x and y of a certain function.
We can be sure it's a linear relationship because, for each increment of 1 in the value of x, the y also increments by 1.
It's required to find the y-intercept of the relationship.
If we look closely at the point (-1, -5) and (1, -3) we can note the point (0, ?) is missing.
We have already stated that, for every increment of 1 for x, the y will also increment by 1, thus, for x = 0, the value of y is y = -5 + 1 = -4
Note this is the mean value between -5 and -3, the two points just around the required answer.
We can also check this result by graphing or finding the equation of the line.
The y-intercept is -4
