Transcript text: Evaluate the expression for \( m \), applying the slope formula.
\[
m=\frac{8-19}{-13-(-13)}
\]
Solution
Solution Steps
To evaluate the expression for \( m \) using the slope formula, we need to substitute the given values into the formula. The slope formula is given by \( m = \frac{y_2 - y_1}{x_2 - x_1} \). In this case, the values are already substituted, so we just need to perform the arithmetic operations in the numerator and the denominator.
Step 1: Identify the Slope Formula
The slope formula for a line passing through two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by:
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
Step 2: Substitute the Given Values
In the given expression, we have:
\[
m = \frac{8 - 19}{-13 - (-13)}
\]
Substitute the values into the slope formula:
\(y_2 = 8\)
\(y_1 = 19\)
\(x_2 = -13\)
\(x_1 = -13\)
Step 3: Simplify the Numerator
Calculate the difference in the \(y\)-coordinates:
\[
8 - 19 = -11
\]
Step 4: Simplify the Denominator
Calculate the difference in the \(x\)-coordinates:
\[
-13 - (-13) = -13 + 13 = 0
\]
Step 5: Evaluate the Expression
Substitute the simplified numerator and denominator back into the expression:
\[
m = \frac{-11}{0}
\]
Since division by zero is undefined, the slope \(m\) is undefined.
