Question 377924: y=2x-8 plot the graphs of the given linear equations using the x and y intercepts and a checkpoint. I don't get it??
Answer by nyc_function(2741)   (Show Source):
You can put this solution on YOUR website! Let x = 0 and solve for y. This will give you one point.
Then let y = 0 and solve for x, this will give you the second point.
=====================================================================
Let x = 0
y = 2x - 8
y = 2(0) - 8
y = 0 - 8
y = -8
The first point to plot is (0,-8).
===================================
Now let y = 0 and solve for x.
y = 2x - 8
0 = 2x - 8
8 = 2x
8/2 = x
4 = x
The second point to plot is (4,0).
Plot both points on graph paper and then connect the points with a straight line.
