Answer: [tex]y=mx+b[/tex]
Step-by-step explanation:
y=mx+b is the equation for a non-proportional relationship. Essentially, you can use this for a proportional relationship as well, since the y-intercept of a proportional relationship will always be zero. [tex]y[/tex] and [tex]x[/tex] are the variables of the equation, and represent the coordinates of the line. [tex]m[/tex] is the slope of the equation. To find the slope, use rise over run, or the change in y between two points over the change in x between two points. The last part is the y-intercept, or [tex]b[/tex]. This shows when the line intercepts the y-axis.
