Question

Nora: d=20+10x
The slope of Nora’s line is

Answer 1

In the equation \( d = 20 + 10x \), the equation can be identified as being in the slope-intercept form of a line, which is \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

Here, comparing with the slope-intercept format:

- The slope \( m \) is represented by the coefficient of \( x \).
- In Nora's equation, the coefficient of \( x \) is \( 10 \).

Thus, the slope of Nora’s line is \( 10 \).
