Labeling the Paper
Slope
Label the exposed flaps with the labels listed
above. You may want to write in pencil, then
write over with magic marker.

Graphing Lines
7
X-intercept pt where the line crosses the
x-axis Y-intercept pt where the line crosses the
y-axis To find the x-intercept plug 0 in for y
and solve for x 2x 4y 8 2x 4(0) 8
2x 8 x 4 To find the
y-intercept plug 0 in for x and solve for y 2x
4y 8 2(0) 4y 8 4y 8
y 2 To graph Find the x-intercept and
y-intercept and then plot the intercepts
and
draw the line connecting them
X-intercept and Y-intercept
