What does [tex]y = mx + b[/tex] mean, and how do you use it to solve problems? What is the difference between [tex]y = mx + b[/tex] and [tex]y = mx + c[/tex]?

Answer (3)

y=mx+c is the equation for a line graph, m is the gradient and c is where it goes through the y axis, the only difference between y=mx+c and y=mx+b is where u live as in different countries learn it different ways but it is still the same thing

In both equations m denotes the gradient and b and c denote the y intercept.
y=mx+b is used for linear equations, finding gradients and y intercepts of lines, finding what points are on and off the line, etc.
Hope that this helped! Best wishes.

The equation y = m x + b describes a straight line, where m is the slope, and b is the y-intercept. The choice of b versus c in the equation has no mathematical difference; they both represent the y-intercept. You can use this equation to find values of y by substituting in values of x .
