Graph the following equation; calculate the slope, x-intercept, and y-intercept, and label the intercepts on the graph.
y = x + 3
-------------
To graph the line, find two points:
Let x=0, then y=3 giving you the point (0,3); this is the y-intercept.
Let y=0, then x=-3 giving you the point (-3.0); this is the x-intercept.
Plot these tow points on an x-y coordinate system.
Draw a line through the two points; that is the graph you want.
-------------
Your equation is in the slope-intercept form:
The slope is the coefficient of "x" which is 1.

This is in slope intercept form highlight%28y=mx%2Bb%29, where m=slope and (0,b)=yintercept
It may help to write your understood "1" in fron of the x:
y=1x%2B3
y=highlight%281%29x%2B3 The slope, m=1
y=1x%2Bhighlight%283%29 The y-intercept, (0,b)=(0,3) (it's at 3 on the y axis.)
Let y=0 and solve for x, to find the x-intercept:
0=x%2B3
0-3=x%2B3-3
-3=x The x-intercept, (-3,0) (it's at -3 on the x axis)
I can't show you the plotted points, but I can show you what the graph looks like after you connect your dots.
