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

Question

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

Answer 1

Plug it into the slope intercept equation:

y=mx + b, where m is the slope and b is the y intercept

Plug in your coordinates for x and y, and plus in your slope for m:

-4 = (2)(2) + b

-4=4 + b

-8 = b

So the y intercept is (0, -8). Plot that point and the point (2, -4) and connect the line.

Answer 2

Draw a graph, put a point where  x(2) and y(-4) meet.  It should be in the lower right quadrant.  Then go up 2 and right one to put a point at (3,-2).  Then draw a straight line through the two points.   Very simple.

Answer 3

You could plot the point (2, -4), and from there use the slope of 2 and go up 2 and then right 1 and plot another point where you end up, and then draw the line going through the two points. You could use more than two points, going to a third point from the second point using the slope.
