The slope ( option A) best describes the number 3.
An equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=7x+2. Where:
a= the slope. It can be calculated for [tex]\frac{\Delta y}{\Delta x}[/tex].
b= the constant term that represents the y-intercept.
For the given example: a=7 and b=2.
The equation of the question is y=3x+7, when you compare this equation with the standard form for the linear equation is: y= ax+b. You find that a=3, where a represents the slope.
