I'm not sure if it is A or B
The second choice is the answer: the initial value is the y value (which is 4) and the rate of change is the slope. The slope is calculated with rise/run, so the rise in this situation is that it moves down (negative) by 3 (rise=-3) and the run is how much it moves to the right (run=4). Therefore, the rate of change is rise/run which is -3/4
Isolate the variable by dividing each side by factors that don't contain the variable.
h = −8
The answer to this question is 1:5
