Answer:

Step-by-step explanation:

The slope-intercept form is found by solving that equation for y.

If $y-3=\frac{1}{2}(x-1)$ then

$y-3=\frac{1}{2}x-\frac{1}{2}$ and

$y=\frac{1}{2}x-\frac{1}{2}+3$ and

$y=\frac{1}{2}x-\frac{1}{2}+\frac{6}{2}$ so

$y=\frac{1}{2}x+\frac{5}{2}$

The answer you have chosen is the correct one! Good job!

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.

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!! Which graph represents

KATRIN_1 [288]

Answer: D

Step-by-step explanation:

Vertex form is: f(x) = a(x - h)² + k where (h, k) is the vertex.

f(x) = (x - 3)² - 5

the vertex is (3, 5).
"a" is positive (+1), so it points upward.

The only graph that matches is the last one, which I called graph D.
