Usually x (independent) variable is the input and y (dependent variable) is the output.
Usually x (independent) variable is the input and y (dependent variable) is the output.
You can graph the line and read out from the graph where the line intersects the X and Y axes. You can input values for Y until you find one that gives an X = 0 and input X values until you find one that gives a Y = 0 (This is the same as setting either X equal to zero and solving the equation the setting Y = 0 and solving)
as the y-intercept increases, the graph of the line shifts up. as the y-intercept decreases, the graph of the line shifts down.
8
The graph of y = x - 8 is a straight line. The slope of the line is 1, and it intersects the y-axis at the point y = -8.
y= -5
The graph is a horizontal line at y=3
It is the line that cuts through the y axis
3
The y-axis is the vertical line on a line graph.
A linear line is just a straight line. To graph it, you can use this equation: y=mx+b where m = the slope of the line, and b = the y-intercept of the line, in other words, where the line crosses the y-axis.
The graph of the equation y=8 is a horizontal line through the y-intercept of 8. This is because since y=8, any point on the graph will have a y-coordinate of 8. This is why it is a horizontal line through (0,8).
