To graph a straight line:

find the y-intercept by taking x = 0

find the x-intercepts by taking y = 0

Draw a straight line joining these two points

change in y depends on the slope.

As x increases:

y increases if the slope is positive

y decreases if the slope is negative

As x decreases:

y increases if the slope is negative

y decreases if the slope is positive
