“Graphing using any two points.”
A. A. State if the following State if the following relations are linear relations are linear function. function.
1. 4x+y 1. 4x+y22=1=1 2.2(x+1)=y 2.2(x+1)=y 3.y=4 3.y=4 4. 4. 5. =y-3 5. =y-3
charmaineWhat is the graph of the linear function?
To find out: Graph each linear function.
1. f(x)=3x-2 2. 4x+3y=12
To determine points that are on To determine points that are on the graph of the given function, the graph of the given function, construct a table of values. Plot construct a table of values. Plot this points and draw a line this points and draw a line through these points.through these points.
