The point of intersection is (-1,3), which is the single solution.
Since there is at least one solution, we can say the equations are consistent.
The y-intercept of y=x+4 is (0,4)
The x-intercept of y=x+4 is (-4,0)
The slope of y=x+4 = 1, so the line slopes up to the right.
The y-intercept of y=-2x+1 is (0,1).
The x=intercept of y=-2x+1 is (1/2,0).
The slope of y=-2x+1 is -2, so the line slopes down to the right.
.
Done.
