Question

Graph the line with slope 2 passing through the point (4,-5)

Answer 1

A slope of 2 is 2/1 = change in y/change in x

plot the point (4, -5)
for every change of +1 in the x, the y changes by +2

so other points would be:
(5,-3), (6,-1), (7,1), (8,3), etc

joint any two points, and it must form a straight line
(notice that finding the slope using any pair you feel like,
will get a slope of 2)
