Question 124051
 Graph the line y = 3x - 4 using the slope-intercept form of the line. What is the Y intercept and what is one other point on the line? 
:
The equation y = 3x - 4 is in the slope/intercept form
:
y intercept occurs when x = 0. If you substitute 0 for x in the above equation:
y = 3(0) - 4
y = 0 - 4
y = -4, this is the y intercept, (pretty simple, right)
:
This point on the graph would be represented by the x,y values: 0, -4
:
To plot a linear graph you need at least one more point.
You can choose a value for x and find y for the 2nd point
:
Let's say x = +2, substitute 2 for x:
:
y = 3(2) - 4
y = 6 - 4
y = 2
;
This point on the graph would be represented by the x,y values: 2, 2
:
A short table of this
 x | y
-------
 0 |-4
+2 |+2
:
Join these points on a graph and it should look like this:
{{{ graph( 300, 200, -6, 5, -10, 10, 3x-4) }}}
Notice that that it crosses (intercepts) the y axis at -4

Did I make this understandable to you?
