Answer:
y = x + 3 is red line.
y = -3x-2 is green line.
y = -x-7 is black line.
y = 2x + 1 is blue line.
Step-by-step explanation:
first we look at up on both and y intercepts
then find a line.
y = x + 3
x intercept is : x + 3 = 0 so x = -3
y intercept is : 0 + 3 = 0 so y = 3
y = -3x-2
x intercept is : -3x-2 = 0 so x = -2/3
y intercept is : -3*0 -2 = 0 so y = -2
y = -x-7
x intercept is : -x -7 = 0 so x = -7
y intercept is : 0 -7 = 0 so y = -7
y = 2x+ 1
x intercept is : 2x+1 = 0 so x = -1/2
y intercept is : 0*2 + 1 = 0 so y = 1
therefor :
Answer:
y = x + 3 is red line.
y = -3x-2 is green line.
y = -x-7 is black line.
y = 2x + 1 is blue line.
I think it is either 10 or 11
Answer: x² + y² = 25
Step-by-step explanation: As we have x²+y²=25 (A) as options,
x-y=1 (B)
x+y=25 (C)
x²+y²=5 (D)
We can rule out B and C as they are not circles. Circles must be
(x - xc)² + (y - yc)² = r². They must have index 2.
We have then A or D.
As the circle must pass through (3,4), we can substitute as x=3 and y=4
(A) 3² + 4² = 9 + 16 = 25 ok
(D) 3² + 4² = 9 + 16 = 25 ≠ 5
So, it is A, x² + y² = 25
