Answer:
The coordinates of the vertex will be (-4,-1)
Step-by-step explanation:
Let's recall that the vertex is in the middle point of the roots of a quadratic function.
The root are <u>(-3,0) and (-5,0) </u>so the x-value of the vertex will be:
The y-value of the vertex is given by the minimum value, that is -1
Therefore, the coordinates of the vertex will be (-4,-1)
I hope it hleps you!

Answer:
y=-3x-2
Step-by-step explanation:
step 1- find the slope
parallel to means same slope, so look at y+3x=4, its not in the correct slope form so we subtract both sides by 3x to get y=-3x+4, the slope is the coefficient of x which is -3. Slope equals 3
step 2- use the point slope form which is y-y1=m(x-x1)
and substitute in the numbers (only substitute y1,x1, and m)
m is the slope which we found to equal -3
x1 and y1 are the points that they gave us (-2,4) are (x1,y1)
x1=-2
y1=4
step 3- substitute
y-y1=m(x-x1)
y-4=-3(x-(-2))
simplifies to y-4=-3x-6
add 4 to both sides to get y=-3x-2
Answer:

Step-by-step explanation:
2. 20×1.5
I am not seeing an equation or a picture but I’ll give you the definition:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
