![m =5](https://img.qammunity.org/2023/formulas/mathematics/high-school/has4wl755sz1rq61odalmxqkvi96ra68nn.png)
Explanation:
================================================
The "constant rate of change" is also known as the slope (in straight line equations).
The equation is in slope-intercept form.
================================================
Slope-Intercept Form is:
![y = mx + b\\ \rule{150}{0.5}\\ \text{m - slope}\\ \text{b - Y-Intercept}](https://img.qammunity.org/2023/formulas/mathematics/high-school/v52wif0ath5rr510a7kuq7zzsoi0quizyg.png)
================================================
Since '5' takes up 'm's spot, it is the slope, or the constant rate of change.
================================================
Hope this helps.
