Complete the equation of the line through (-9,7) & (-6,-3)
scZoUnD [109]

Answer:

y=-\frac{10}{3}x-23

Step-by-step explanation:

we have the points

(-9,7) and (-6,-3)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{-3-7}{-6+9}

m=-\frac{10}{3}

step 2

Find the equation in point slope form

y-y1=m(x-x1)

we have

m=-\frac{10}{3}

(x1,y1)=(-6,-3)

substitute

y+3=-\frac{10}{3}(x+6)  ---> equation in point slope form

step 3

Find the equation of the line in slope intercept form

y=mx+b

we have

y+3=-\frac{10}{3}(x+6)

Isolate the variable y

Distribute right side

y+3=-\frac{10}{3}x-20

subtract 3 both sides

y=-\frac{10}{3}x-20-3

y=-\frac{10}{3}x-23

Rotate the vector (0,2) 270 degrees counterclockwise about the origin
SashulF [63]
<h3>Answer:  (2,0)</h3>

Explanation:

The vector (0,2) points directly north and the length of this vector is 2 units. It's the distance from (0,0) to (0,2).

When rotating 270 degrees counterclockwise, we'll turn to the left or westward direction (90 degrees so far) then at some point aim directly south (180 degrees so far) and finally ultimately end up pointing directly east (after getting to 270). So that's how we go from (0,2) to (2,0).

If you were to go clockwise, then everything flips and you'll ultimately end up pointing directly west. The length of the vector stays the same the whole time.

I need help with this pls
Alexxx [7]

Hello!

<u>What is an x-intercept</u>:

 ⇒ <em>value of x</em> when the <em>value of y</em> equals '0'

       8x + 5y=25\\8x+5(0)=25\\8x=25\\\\x=\dfrac{25}{8}

  x-intercept is <u>25/8</u>

<u></u>

<u></u>

<u>What is a y-intercept:</u>

 ⇒ <em>value of y</em> when the <em>value of x</em> equals '0'

       8x+5y=25\\8(0)+5y=25\\5y=25\\y=5

   y-intercept is <u>5</u>

<u></u>

Hope that helps!
