Question

hi everyone, I'm studying for a math test. I just have one specific question: are all equations in the format y=mx+b linear equations? Or do I still need to graph it and check if it is a straight line first??

Answer 1

Yes, all equations in the format y=mx+b are linear equations. In this format, "m" represents the slope of the line and "b" represents the y-intercept, which is the point where the line intersects the y-axis. This means that all equations in this format will produce a straight line when graphed.

However, it is always good practice to graph the equation to confirm that it is a straight line. This will also allow you to see the slope and y-intercept of the line, and check if they match the values of "m" and "b" in the equation.

Answer 2

All equations in y=mx + b form are linear equations. There is no need for graphing :)
