Let A be (2,-1) & B be (3,4). The radius of the circle is AB. Let's calculate it

AB =√{(3-2)²+(4+1)²]  = √26

Now the standard form of the equation of a circle:

(x-h)²+(y-k)² = R²

(x-2)²+(y-1)² = 26

write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x+y=-5. include your work in
Readme [11.4K]
Parallel to 2x+y=-5
2x+y-2x=-5-2x
y=-2x-5
y=mx+b
Slope: m=-2

As the line is parallel must have the same slope:
m=-2
And it has an x-intercept of 2: when x=2, y=0→Point: P1=(2,0)=(x1,y1)
x1=2, y1=0

y-y1=m(x-x1)
y-0=(-2)(x-2)
y=-2x+4
In standard form:
y+2x=-2x+2x+4
2x+y=4

Answer: The equation of the line, in standard form, that passes through the origin and is parallel to x+y=6 is x+y=0

nikitadnepr [17]
Since there are 9 hockey cards per page and it holds 900 hockey cards you can multiply 9 by 68 to get the total of 612 hockey cards. Then take 900 and subtract 612 from it and you should get 288 hockey cards in the album. Then divide that number by 9 to get the total number of pages filled 288/9=32 pages filled
