Explanation:
To express the equation 2x + y = -7 in slope-intercept form (y = mx + b), where 'm' is the slope and 'b' is the y-intercept, follow these steps:
1. Subtract 2x from both sides of the equation:
y = -2x - 7
Now, the equation is in slope-intercept form, and the slope 'm' is -2, while the y-intercept 'b' is -7.
Hopefully this helps! :)
