Answer:
Step-by-step explanation:
Add 
to both sides
Divide both sides by 11
The x-intercept is 3 and the y-intercept is -2
Answer:
The slope is 5x and the y-intercept is -7
Step-by-step explanation:
Answers:
- y intercept: 9
- zeros: -3, -1, 1, 3
===============================================
Explanation:
The y intercept is where the curve crosses the y axis. The curve appears to do so just below y = 10, so y = 9 seems like a good estimate. I'm basing this off of the answer choices given. The y intercept always occurs when x = 0.
The zeros, aka roots or x intercepts, are where the curve crosses or touches the x axis. This occurs in four locations: x = -3, x = -1, x = 1 and x = 3. The x intercepts always occur when y = 0.
