It looks like you've provided values for $m$ (slope) and $b$ (y-intercept), which are likely for the equation of a straight line in slope-intercept form:

$y = mx + b$

Given that $m = 1$ and $b = -7$, the equation of the line becomes:

$y = x - 7$

This equation represents a straight line with a slope of 1 and a y-intercept of -7.

Would you like more details or have any questions?

Here are 5 related questions to consider:

1. How do you graph the line $y = x - 7$?
2. What is the significance of the slope and y-intercept in this equation?
3. How do you find the x-intercept of the line $y = x - 7$?
4. How would the graph change if the slope $m$ were different?
5. How do you solve for $x$ when $y = 0$ in the equation $y = x - 7$?

Tip: To graph a line, you can start by plotting the y-intercept and then use the slope to find other points on the line.
