Find the distance between the endpoints (7,8) (4,2) A.10.8 B.2.2 C.6.7 D.14.9
Paha777 [63]

Answer:

\boxed{  \bold{ \huge{ \boxed{ \sf{6.7}}}}}

Option C is the correct option.

Step-by-step explanation:

Let the points be A and B

Let A ( 7 , 8 ) be ( x₁ , y₁ ) and B ( 4 , 2 ) be ( x₂ , y₂ )

<u>Finding</u><u> </u><u>the</u><u> </u><u>distance</u><u> </u><u>between</u><u> </u><u>these</u><u> </u><u>points</u>

\boxed{ \sf{distance \:  =  \:  \sqrt{ {(x2 - x1)}^{2} +  {(y2 - y1)}^{2}  } }}

\dashrightarrow{ \sf{ \sqrt{ {(4 - 7)}^{2}  +  {(2 - 8)}^{2} } }}

\dashrightarrow{ \sf{ \sqrt{ {(  - 3)}^{2} +  { (- 6)}^{2}  } }}

\dashrightarrow{ \sf{ \sqrt{9 + 36}}}

\dashrightarrow {\sf{ \sqrt{45} }}

\dashrightarrow{ \sf{6.7 \:  \: units}}

Hope I helped!

Use the information given to enter an equation in standard form.
Greeley [361]

Answer:

y = -2x + 25

Step-by-step explanation:

A standard equation can be in slope-intercept form: y = mx + b

m is the slope, b is the y-intercept.

Plug in the given slope.

y = -2x + b

To find b, plug in the given point (9, 7).

7 = -2(9) + b

Multiply.

7 = -18 + b

Add 18 to both sides to find b.

25 = b

Plug this into your standard equation.

y = -2x + 25

Check by plugging in the given point again.

7 = -2(9) + 25

7 = -18 + 25

7 = 7

Your answer is correct!

Hope this helps!
