Chapter 3: Q22. (page 179)

Find the value of r so the line that passes through the pair of points has the given slope.
$(鈭� 4, 8) (r, 12), m = \frac{4}{3}$
F $鈭� 4$
G $鈭� 1$
H 0
J 3

Short Answer

The option G $(鈭� 1)$ represents the required value.

Step by step solution

Step 1. Determine the formula that can be used.

The slope formula $m = \frac{y_{2} 鈭� y_{1}}{x_{2} 鈭� x_{1}}$ can be used to calculate the required value.

Step 2. Take the help of the obtained method.

Take the help of formula for slope of a line represented by $m = \frac{y_{2} 鈭� y_{1}}{x_{2} 鈭� x_{1}}$ in which the required values can be filled by using the provided points and slope as the points are in the form of $(x_{1}, y_{1}) (x_{2}, y_{2})$ .

$\frac{4}{3} = \frac{12 鈭� 8}{r 鈭� (鈭� 4)} \frac{4}{3} = \frac{4}{r + 4} \frac{4}{3} 鈰� 3 = \frac{4}{r + 4} 鈰� 3 4 = \frac{12}{r + 4} 4 (r + 4) = \frac{12}{r + 4} 鈰� (r + 4) 4 r + 16 = 12 4 r + 16 鈭� 16 = 12 鈭� 16 4 r = 鈭� 4 \frac{4 r}{4} = \frac{鈭� 4}{4} r = 鈭� 1$

Step 3. Write the conclusion.

The value of r is $鈭� 1$ so it is the required value.
