y=mx+b
m=slope
b= y intercept (when x = 0
y= y value
x=x value
you already have your slope given plug in you x and y values into the equation and reverse the math, like you would do to "solve for X this time B"
you will then get you whole equation
Answer:
The equation of the quadratic in standard form is:
Step-by-step explanation:
Since they give us the information about where the vertex of the parabola is located, and one extra points where it passes through, we can use the general form of a quadratic in vertex form:
where is the location of the vertex (in our case the point (-2,6).
Therefore the equation above becomes:
Now,we can use the fact that the point (-4,-2) is also a point of the graph, to find the value of the parameter :
Then, the equation of the quadratic with such characteristics becomes:
which is the equation of the quadratic in standard form.
