your given information is important because your first piece of info is the y intercept. The y intercept can be interpreted as (0,2). this is your initial point.
once you have that point, you can then use the slope to finish off your linear function. the slope is rise/run.
this means that you have to travel in the y direction, which is your rise. this means you have to go either in the positive or negative, depending on the number. in this case, it's -6, so we would go down 6.
then we would run 5 units in the x direction and same like the x it would be depending on the number being positive or negative. since we have a +5 it means we have to move 5 units to the right should have a graph that looks like a (\).
hope it helps.
