Write the quadratic equation y=x^2-6+7 in vertex form

1 answer:

7 0

Half the x-coefficient is -3, so the equation needs to be rearranged into a form that looks like
x² -6x +(-3)² + [something]
You can get there by adding and subtracting 9 from the original equation.
y = x² -6x +9 +7 -9 . . . . . 9 added and subtracted
y = (x² -6x +9) -2
The quantity in parentheses is a perfect square, so we can write the equation in the desired form as ...
y = (x -3)² -2

What is the slope of this graph

Elden [556K]

Answer:

The slope of the line = m = 2

Step-by-step explanation:

Given

The points

(0, 0)

(1, 2)

To determine:

The slope of this graph

Determining the slope between (0, 0) and (1, 2)

(x₁, y₁) = (0, 0)

(x₂, y₂) = (1, 2)

Using the formula

Slope = m = [y₂ - y₁] / [x₂ - x₁]

= [2 - 0] / [1 - 0]

= 2 / 1

Thus, the slope of the line = m = 2
