Answer:

(1,2) is the solution to both lines a and b

Step-by-step explanation:

You find the slope using 2 point and do y2-y1/x2-x1 . To create the equations for the two lines you do y=mx+b where m=slope and b=y-intercept.

Find the area of a circle with a circumference of <br> 18.84
Anton [14]

Answer:

9π OR 28.26

Step-by-step explanation:

The formula for circumference is C = 2πr.

Substitute circumference = 18.84 for C.

18.84 = 2πr

Work backwards to find the radius of your circle.

\frac{18.84}{2(3.14)} =r

r = 3

Now, use the formula for the area of a circle: A = πr^2.

Substitute r = 3 into the equation:

A = π 3^2 = 9π ≈ 28.26

Write the equation of the line that passes through the points (-7,9) and (-7,1). Put your answer in fully reduced point-slope fo
gulaghasi [49]

Answer:

It is a vertical line

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(1 - 9) / (-7 + 7)

-8/0

= undefined

Dividing by 0 gives you an undefined number. This means that the slope is undefined, and the line is a vertical line.
