Answer:

2

Explanation:

As x increases from -28 to -14, a change of +14 units, the value of y increases from -54 to -26, a change of -26+54 = 28 units.

If x increases 14 more units to 0, y will increase 28 more units from -26 to +2.

The y-intercept is +2.

_____

We have determined the slope to be (change in y)/(change in x) = 28/14 = 2, so the relation between x and y is ...

y = 2x +2
