Question 138299
graph each system of equations on the same set of axes.name the point of intersection.y=3x+1   y=x-1
--------------------------------
Graph equation y = 3x + 1
You need two points:
If x = 0, y = 3*0+1, so y = 1
If x = 1, y = 3*1+1, so y = 4
Plot the two points (0,1) and (1,4)
Draw a line thru them to get:
{{{graph(400,300,-10,10,-10,10,3x+1)}}}
----------------------------
Graph equation y = x-1
You need two points:
If x = 0 , y = 0-1, so y = -1
If x = 1 , y = 1-1, so y = 0
Plot the two points ( 0,-1) and (1,0)
Daw a line thru them to get:
{{{graph(400,300,-10,10,-10,10,x-1)}}}
-------------------------------------------
Now graph both of those line on the same set of axes to get:
{{{graph(400,300,-10,10,-10,10,3x+1,x-1)}}}
---------------------------------------------
The point of intersection is the solution for the set of equations.
It is (-1,-2)
