How would i graph this equation y=3x+1
Kipish [7]

Answer:

(0,1)(1,4)

Step-by-step explanation:

Put in any value of x to find y, then you have a coordinate, then plot it

lets say i pick 0 for x

y = 3(0) + 1

y = 1

(0,1)

lets say i also pick 1 for x

y = 3(1)+1

y = 4

You need atleast two points to plot a line, these are two points.
