Equation of a Line in ‘Slope y-intercept’ Form
We describe lines on the graph using __________ ___________ or equation of a line.
Equation of a line can be expressed in 2 different forms.
Equation of a Line
Standard Form
Slope Y-intercept Form
�� = ���� + ��
①
Graphing
(Slope y-intercept Form)
The y-intercept acts as the initial point that we use to plot our line.
Slope tells us where to plot the other points which we then connect to form a line.
Step 1:
Plot y-intercept
Step 2:
Check to see if the slope is a fraction (if not, then convert it to fraction)
Step 3:
Plot the next point using the slope
Numerator

) or _________ (
)
Graph �� = 5�� + 4
Graph �� = −
