The square root of 18 is 4.24
Answer:
y = –7x – 11
6x – 4y = 10
Step-by-step explanation:
From the question given above, we obtained:
x = –1
y = –4
y = ?x – 11 ....... (1)
6x – ?y = 10b......... (2)
Let the two unknown be a and b. Thus the above equation becomes:
y = ax – 11 ......... (3)
6x – by = 10 .......(4)
Next, we shall determine the value of 'a' and 'b'. This can be obtained as follow:
For a:
y = ax – 11
x = –1
y = –4
–4 = a(–1) – 11
–4 = –a – 11
Collect like terms
–4 + 11 = –a
7 = –a
Multiply through by –1
a = –7
For b:
6x – by = 10
x = –1
y = –4
6(–1) – b(–4) = 10
–6 + 4b = 10
Collect like terms
4b = 10 + 6
4b = 16
Divide both side by 4
b = 16 / 4
b = 4
Finally, we shall substitute the value of a and be into equation 3 and 4 respectively.
y = ax – 11
a = –7
y = –7x – 11
6x – by = 10
b = 4
6x – 4y = 10
Therefore, the complete equation are:
y = –7x – 11
6x – 4y = 10
if its diameter is 34, then its radius is half that or 17.

Answer:
The correct answer would be -2x + y = -10
Step-by-step explanation:
To do this, start with point-slope form and input the known values.
y - y1 = m(x - x1)
y + 2 = 2(x - 4)
Now distribute and solve for the constant.
y + 2 = 2(x - 4)
y + 2 = 2x - 8
-2x + y + 2 = -8
-2x + y = -10
3 5/10 - 2/5
35/10 - 2/5
35/10 - 4/10
31/10=3 1/10 or 3.1
