Answer:
Its A
Step-by-step explanation:
I think you multiply 17×9 which equals 153 and then multiply 68×36 which equals 2,448 and then add 2,448+153 which equals 2,601
X² + y² - 4 x + 2 y = b
x² - 4 x + 4 + y² + 2 y + 1 = b + 4 + 1
( x - 2 )² + ( y + 1 )² = b + 5
y - coordinate of the center of the circle is: y = - 1
b + 5 = r
b + 5 = 7
b = 7 - 5
b = 2

Step-by-step explanation:
Answer: y=3x+1
Step-by-step explanation:
First find slope using formula
m= y2–y1/x2–x1
m= 4– (—2)/ 1— (—1)
m= 3
So,
y= mx+b
y=3x+b. Using (1,4) plug into equation of a line
4= 3(1)+b
4 – 3= b
1= b. So,
y=3x+1
