Chapter 4: Q8. (page 275)

Write an equation of the line in slope-intercept form that passes through the given points.
$(7, - 1)$ , $(9, - 4)$

Short Answer

Expert verified

The required equation is represented by $y = \frac{- 3}{2} x + \frac{19}{2}$ .

Step by step solution

Step 1. Determine the formula that can be used.

The standard form associated with line that is having a travel through points which are two in count $y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} (x - x_{1})$ can be used to calculate the required equation.

Step 2. Take the help of the obtained method.

Take the help of obtained standard form represented by $y - y_{1} = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} (x - x_{1})$ in which the required values can be filled by using the provided points as they are in the form of $(x_{1}, y_{1})$ $(x_{2}, y_{2})$ .

localid="1647432446752" $y - (- 1) = \frac{- 4 - (- 1)}{9 - 7} (x - 7) y + 1 = \frac{- 3}{2} (x - 7) y = \frac{- 3}{2} (x) + \frac{21}{2} - 1 y = \frac{- 3}{2} x + \frac{19}{2}$

Step 3. Write the conclusion.

The obtained equation is $y = \frac{- 3}{2} x + \frac{19}{2}$ so it is the required equation.
