Math Problem Statement
Find the slope and y-intercept of the line -2x + y = -4.
Solution
The equation provided in the image is:
To find the slope and the y-intercept, we need to rewrite the equation in slope-intercept form, , where is the slope and is the y-intercept.
- Solve for :
Now, we can identify:
- The slope is .
- The y-intercept is .
Thus, the slope is , and the y-intercept is .
