Answer: 2
Explanation: This linear equation is written in slope-intercept form where is more commonly know as y = mx + b form where the multiplier, m, or the coefficient of the x term represents the slope of the line and the b or the constant term represents the y-intercept of the line.
So by looking at this linear equation, we can identify that the slope is 2 because it's your coefficient of the x term or the number in front of x.
