Answer:
y = -4x + 2
Step-by-step explanation:
- We know that the equation of slope is y = mx + b
- We also know that the slope is -4 given in this problem
- So:
- y = -4x + b
- Using the point (-1, 6), we can substitute this point into the above equation to solve for b.
- (6) = -4(-1) + b
- 6 = 4 + b
- b = 2
- Therefore the equation of the line is y = -4x + 2

Answer:
See below
Step-by-step explanation:
<u>Part A</u>
Remember that x-intercepts are located where y=0:
<u />
<u /><u />
<u /><u />
<u /><u />
<u /><u />
<u /><u />
<u /> and
<u>Part B</u>
Since the leading coefficient, -16, is negative, the parabola will open downward, making the vertex a maximum. We can determine the x-coordinate of the vertex using and plug it into the function to find the y-coordinate:
Now we find the y-coordinate given the x-coordinate:
Therefore, the coordinates of the vertex are .
<u>Part C:</u>
Notable points of a quadratic function include its x-intercepts, y-intercept, and vertex. Plotting these points on a graph help to visualize what the resulting graph of the function looks like. I've attached a graph with the function and the notable points for you to see.
