Greetings!This a line/equation represented in the
slope y-intercept form:
1)
Coordinates of a point in the line are shown by
y and
x.
2) The variable
m represents the
slope of the line.
3) The variable
b represents the
y-intercept (when the line hits the y-axis) of the line.
We only need 2 pieces of the information (listed above) in order to graph the line.
Using the information provided by the equation...
...we can graph the line.
We know that the slope is 3 (also shown as
) as m=3 We also know one of the coordinate points (0,-2) due to the y-intercept. Now, we can graph:
1) Plot your first coordinate point.
2)
Your next point would be 3 sqaures up and 1 square to the right (or 3 sqaures down and 1 square to the left; Doesn't really matter as:
This would result in a second coordiante point of
(1,1) Now that you have two points on the plane, you can use a ruler and pencil to connect the points, forming the line which represents the equation.
Hope this helped!
