Answer:

y = -2x + 9

Step-by-step explanation:

Using the slope intercept equation y=mx+b, we can see that the slope of the line parallel to y = -2x + 7 is -2.

m = -2

Use the point slope formula y - y1 = m(x - x1) to find the line that runs through (4,1)

y - 1 = -2(x - 4)

Simplify

y - 1 = -2x + 8

y = -2x + 9

You can check your answer by putting in the point and seeing if the equaiton is true

1 = -2(4) + 9

1 = -8 + 9

1 = 1

True

What are the coordinates of the vertex of the function below? Write your answer in the form (x,y).

DerKrebs [107]

ANSWER

The vertex is

$(5,11)$

EXPLANATION

The given function is

$y - 11 = - {(x - 5)}^{2}$

Rewrite in the form;

$y = - {(x - 5)}^{2} + 11$

This function is in the form;

$y = a {(x - h)}^{2} + k$

where

$(h,k)=(5,11)$

is the vertex

Heres a graph of a linear function. Write the equation that describes that function.

Virty [35]

Answer:

Y= $\frac{1}{3}$ X-4

Step-by-step explanation:

Using the slope-intercept equation, a line is given as y=mx+b, where m represents the slope and b represents the y-intercept. From this graph, we can see that the slope is 1/3 and this line meets the y-axis at -4.

Thus, using that information, we substitute this into the equation to get

y= (1/3)x - 4
