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
