The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-8, -8) and (-7, 9). Substitute to the formula of a slope:

m=\dfrac{9-(-8)}{-7-(-8)}=\dfrac{17}{1}=17

Put the coordinates of the point (-7, 9) and the value of slope to the point-slope formula:

y-9=17(x-(-7))\\\\\boxed{y-9=17(x+7)}

What is the equation in point-slope form of the line passing through (−2, 0) and (2, 8)? (1 point) y = 2(x + 2) y = 2(x − 2) y =
Sonja [21]

Answer: y=2(x+2)

Step-by-step explanation:

The slope of the line is

y=\frac{8-0}{2-(-2)}=\frac{8}{4}=2

Using the point (-2, 0) to substitute into point-slope form, we get the equation to be \boxed{y=2(x+2)}

Line CH contains points (-2, 6) and H(5, -3) What is the slope of G?
Xelga [282]

Answer:

The slope of line G is \dfrac{- 9}{7}  .

Step-by-step explanation:

Given as :

The points of the line CH contains

C = x_1 ,  y_1 = - 2 , 6

H = x_2 ,  y_2 = 5 , -3

Let The slop of line CH = G

<u>Now, slope of line is </u>

G = \dfrac{y_2 - y_1}{x_2-x_1}

i.e G = \dfrac{- 3 - 6}{5 -(-2)}

Or, G = \dfrac{- 9}{5 +2}

Or,G = \dfrac{- 9}{7}

So, The slope of the line CH = G = \dfrac{- 9}{7}

Hence, The slope of line G is \dfrac{- 9}{7}  . Answer

0.45 plus 9x equals 27
oee [108]

Answer:

x = 2.95

Step-by-step explanation:

<u>Step 1:  Convert words into an expression</u>

0.45 plus 9x equals 27

0.45 + 9x = 27

<u>Step 2:  Solve for x</u>

0.45 + 9x - 0.45 = 27 - 0.45

9x / 9 = 26.55 / 9

x = 2.95

Answer:  x = 2.95
