Identifying Linear Functions, FIND "X" AND "Y" INTERCEPTS
Not a linear function because x and y are being multiplied.
2xy + y = 4
Definition of Linear Function
Any function that graphs to a straight line
(-5,0) (0,-4)
FIND THE X/Y INTERCEPTS FOR THE FOLLOWING EQUATION... -4X - 5Y = 20
(6,0) (0,4)
FIND THE X/Y INTERCEPTS FOR THE FOLLOWING EQUATION... 2X + 3Y = 12
(5,0) (0,10)
FIND THE X/Y INTERCEPTS FOR THE FOLLOWING EQUATION... 2X + Y = 10
(5,0) (0,3)
FIND THE X/Y INTERCEPTS FOR THE FOLLOWING EQUATION... 3X + 5Y = 15
(8,0) (0,4)
FIND THE X/Y INTERCEPTS FOR THE FOLLOWING EQUATION... 4X + 8Y = 32
(6,0) (0,9)
FIND THE X/Y INTERCEPTS FOR THE FOLLOWING EQUATION... 6X + 4Y = 36
(-10,0) (0,5)
FIND THE X/Y INTERCEPTS OF THE FOLLOWING EQUATION... -2X + 4Y = 20
linear equation
any equation that can be written in the standard form
x-intercept
the x-coordinate of the point where the graph intersects the x-axis.
y-intercept
the y-coordinate of the point where teh graph intersects the y-axis.
Not a function because it makes a vertical line.
x=3
Linear function because it makes a horizontal graph
y=3
