I believe it's 15, but correct me if I'm wrong
This is because there is one 10 in 15. This gives you 3 tens and 5 in the ones.

Find the slope in (-2,8) and (1,6)

Salsk061 [2.6K]

Formula for slope: $\frac{y2 - y1}{x2 - x1}$

y₂: 6

y₁: 8

x₂: 1

x₁: -2

Plug them into the slope equation:

$\frac{6 - 8}{1 - (-2)}$

--> $\frac{-2}{1 + 2}$

---> $-\frac{2}{3}$

The slope is $-\frac{2}{3}$ .

Which of the equations below could be the equation of this parabola?

Mademuasel [1]

Answer:

Option B: $y = -\frac{1}{2} x^2$

Step-by-step explanation:

The parabola has its concavity downwards, so we need a function in the model:

$y = ax^2 + bx + c$

With a negative value of 'a'

The vertex is (0,0), so we have that:

$0 = 0a + 0b + c$

$c = 0$

The x-coordinate of the vertex is given by the equation:

$x\_vertex = -b/2a$

$-b/2a = 0$

$b = 0$

So we have a function in the model:

$y = ax^2$

With a < 0

The only option with this format is B:

$y = -\frac{1}{2} x^2$
