Standard Form:
Ax  By  C
Where A, B, and C are coefficients, and x
and y are our variables.

X & Y Intercept
y – intercept: Where the line crosses
the y axis (X IS ZERO)
x – intercept: Where the line crosses
the x axis (Y IS ZERO)

Finding X&Y Intercepts
5x – 4y = 20
+
Finding X&Y Intercepts
x – y = 10

Finding X&Y Intercepts
3x + 8y = 16
1)x – 3y = 6
2) 2x + y = 4
3) 5x – 2y = 10
1) x – 2y = -4
2) x + 2y = 0
3) 2x + 3y = 6
4) 2x + y = 1
