Q. Find the slope of the line y+4=21(x+13). Write your answer as an integer or as a simplified proper or improper fraction.
Identify Form: Identify the form of the equation.The equation y+4=21(x+13) is in the point-slope form, which is y−y1=m(x−x1), where m is the slope of the line.
Compare with Point-Slope Form: Compare the given equation with the point-slope form. The given equation y+4=21(x+13) can be compared to the point-slope form y−y1=m(x−x1) to identify the slope m.
Identify Slope: Identify the slope from the equation.By comparing, we can see that the slope m is the coefficient of (x+13), which is 21. Therefore, the slope of the line is 21.
