Can someone please help me
1 answer:
The slope is ...
... m = (change in y)/(change in x) = (-53 -24)/(7-(-4)) = -77/11 = -7
Using the first point, the equation is ...
... y - 24 = -7(x + 4)
______
The line with slope m through point (h, k) is given by
... y - k = m(x - h)
The signs in your given equation are such that the point coordinate values cannot be used directly.

Step-by-step explanation:
When a parabola has the form , It is vertical (opens up or down).
Because the variable "x" is squared.
If "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.
In this case you have the quadratic function:
Which can be rewritten as:
Therefore, it is vertical, because it has the form:
You can observe that the value of "a" is:
Then, since "a" is positive, the parabola opens up.
