Q. find the slope of the line (y = \frac{2}{9}x + \frac{6}{13}).
Answer
The line is \(y = \frac{2}{9}x + \frac{6}{13}\). In slope–intercept form \(y = mx + b\) the slope \(m\) is the coefficient of \(x\), so \(m = \frac{2}{9}\). Final result: slope = \(\frac{2}{9}\).
Detailed Explanation
Find the slope of the line
-
Recognize the slope-intercept form of a line. A linear equation in slope-intercept form is written as
\(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept. -
Compare the given equation to the slope-intercept form. The given equation is
\(y = \tfrac{2}{9}x + \tfrac{6}{13}\).Here the coefficient of \(x\) is \(\tfrac{2}{9}\), so that coefficient is the slope.
-
State the slope. The slope of the line is
\(\displaystyle m = \tfrac{2}{9}\). -
Optional verification (using two points on the line). Evaluate the line at \(x=0\) to get the y-intercept:
\(y(0) = \tfrac{6}{13}\), giving point \((0,\tfrac{6}{13})\).Evaluate the line at \(x=9\):
\(y(9) = \tfrac{2}{9}\cdot 9 + \tfrac{6}{13} = 2 + \tfrac{6}{13} = \tfrac{32}{13}\), giving point \((9,\tfrac{32}{13})\).Compute the slope between these two points:
\(\dfrac{\tfrac{32}{13} – \tfrac{6}{13}}{9 – 0} = \dfrac{\tfrac{26}{13}}{9} = \dfrac{2}{9}\), which matches the coefficient found earlier.
