Answer:

$\boxed{\sf{m=\frac{4}{5}}}$

Step-by-step explanation:

In order to solve this problem, we will use the slope.

Slope:

$\sf\dfrac{Y_2-Y_1}{x_2-x_1}=\dfrac{rise}{run}$

y2=(-6)

y1=(-2)

x2=2

x1=7

Solve the problem by rewriting it down.

$\sf{\dfrac{(-6)-(-2)}{2-7} }=\dfrac{(-6)+2}{2-7}=\boxed{\dfrac{4}{5} }$

Therefore, the slope is 4/5.

I hope this helps! Feel free to correct me if I am wrong.

Minchanka [31]

Answer:

2/3 min

Step-by-step explanation:

We can write these as equations

so 8-2.5x=5-0.5x

We isolate x by subtracting both sides by 5

3-2.5x=0.5x

add 2.5x to both sides

3=2x

divide both sides by 2

x=2/3min

Graph y = x2 + 2. Identify the vertex of the graph. Tell whether it is a minimum or maximum. (0, 2); maximum (0, 2); minimum (2,

miskamm [114]

Answer:

$(0,2)$ ; minimum

Step-by-step explanation:

Given:

The function is, $y=x^{2}+2$

The given function represent a parabola and can be expressed in vertex form as:

$y=(x-0)^{2}+2$

The vertex form of a parabola is $y=(x-h)^{2}+k$ , where, $(h,k)$ is the vertex.

So, the vertex is $(0,2)$ .

In order to graph the given parabola, we find some points on it.

Let $x=-2,y=(-2)^{2}+2=4+2=6$

$x=-1,y=(-1)^{2}+2=1+2=3$

$x=0,y=(0)^{2}+2=0+2=2$

$x=2,y=(2)^{2}+2=4+2=6$

$x=1,y=(1)^{2}+2=1+2=3$

So, the points are $(-2,6),(-1,3),(0,2),(1,3),(2,6)$ .

Mark these points on the graph and join them using a smooth curve.

The graph is shown below.

From the graph, we conclude that at the vertex $(0,2)$ , it is minimum.
