Graphing More Lines

Now let's put two concepts together to graph lines anywhere on the

coordinate plane.

Let's review what we've gone over so far.

1) Graphing points on the coordinate plane is easy as

long as you remember to move left or right first and

then up or down. Remember to always start at the

origin.

2) The slope of a line is how steep it is. It is often

referred to as rise over run, because it's the change

in the x values divided by the change in the y values.

3) Graphing lines is easy when they are in

y = mx = b form. Always start at the intercept and

move according to the given slope.

To graph lines using a given point and slope is easy. First plot the point

and then use the slope to plot a second. Connect the two and you're done !

 

In order to do this, you'll need some graph paper.

 

Plot the following lines on your coordinate plane and show them to me

tomorrow. Good Luck !!

Line 1 m = 5, through the point ( 3, 2 )

Line 2 m = -2, through the point ( -5, -2 )

Line 3 m = .5, through the point ( 0, -4 )

Line 4 m = 3/2, through the point ( -3, -5 )

Line 5 m = -3/5, through the point ( 1, 1 )
