This document discusses how to graph linear functions by identifying the y-intercept and slope. It explains that the y-intercept is the point where the line crosses the y-axis, while the slope is the rise over run and written as a fraction. It provides instructions to locate the y-intercept, use the slope to find another point, and connect the points to graph the linear function. Students are then directed to graph several linear functions using given slopes and y-intercepts and write the coordinates of new points.

5. Any line in the
coordinate plane has y-
intercept b if it
intersects the y-axis at a
point (0,b). Therefore
the graph of linear
function can also be
drawn if the y-intercept

6. The y-intercept
or b has the
coordinate
(o,b).

7. The slope or m,
on the other hand,
is the rise and run,
and often written
in fraction form.

9. Locate the y-
intercept in the y-
axis.

10. With the intercept as
the starting point,
determine another point
using the given slope.

11. Connect points to
obtain the graph of
linear function.

15. Directions: Graph the
linear function using
the given slopes and y-
intercepts. What shape
is formed from the
different lines?

20. Directions: Plot the given slopes
and points on the Cartesian
plane. Write the coordinates of
the new points formed.
1. b = -2 ; m = 3/7
2. b = -4 ; m = 5/8
3. b = 1 ; m = 4/5
