An easy way of solving this equation involves the use of a table. List several arbitrary x values on the left side and then their respective y values in the right side of the table:
X Y
0 4
1 5
2 6
3 7
4 8
5 9
With the x and y values shown on the above chart, plot these values on a graph and it will depict a diagonal line intersecting the y-axis at 4 and intersecting the x-axis at -4.
the graph is moved down 6 units
First convert it to Y= y-x+4=0 y=x-4 The graph has a slope of 1 and the y-intercept is (0,-4)
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x

there is no right answer
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
y=-10x-4
the graph is moved down 6 units
First convert it to Y= y-x+4=0 y=x-4 The graph has a slope of 1 and the y-intercept is (0,-4)
y=x+1 there for answer is 2
y = x2 + 4 The graph is a parabola, with its nose at y=4 on the y-axis, and opening upward.
Upwards.
-9
y = -0.5x plus or minus any number
Infinite, both equations are equivalent and all possible solutions can be represented on the graph y = 4 - x
(0,4) and (-2, 0)
