The graph would be translated upwards by 2 units.
The answer will depend on what was changed to what!
A bar graph would be the best graph or chart to use to compare and contrast information.
A Bar Graph
It would be less steep.
That would be a linear equation.
line graph
If you mean y = x+4 and y = x-2 then the slopes would be parallel but with different y intercepts
The graph of an equation is all of the answers that are true for the equation. A variable is an unknown number in an equation. Most equations are written with x and y variables. There are an unlimited amount of numbers that the variables can be to have the equation be true, so you would graph the equation to show the unlimited amount of numbers that make the equation true.
Move 3 over the right side of the equation so the equation would be x = -3. The graph of this would be a verticle line at x= -3
It would be shifted down
The question contains an expression, not an equation. An expression does not have a graph. Furthermore, even if it were an equation, its form suggests that it would be a linear equation and a linear equation does not open in any direction.
