3 Find y if the slope between ( – 7, y) and (1, 13) is 3/4​

Mathematics
1 answer:
mafiozo [28]3 years ago
3 0

Step-by-step explanation:

slope \:  =  \frac{y2  - y1}{x2 - x1}  =  \frac{3}{4}

point 1 ( -7,y)

point 2 (1,13)

\frac{13 - y1}{1 - ( - 7)}  =  \frac{3}{4}

\frac{13 - y1}{8}  =  \frac{3}{4}

13 - y2 =  \frac{8 \times 3}{4}  = 6

y2 = 13 - 6 = 7

y = 7

The standard form of the equation of a circle is (x−5)2+(y−6)2=1.
Crank

Answer:

(A)x^2+y^2-10x-12y+60=0

Step-by-step explanation:

The standard form of the equation of a circle is given as:

(x-5)^2+(y-6)^2=1

Simplifying the above given equation, we get

x^2+25-10x+y^2+36-12y=1

x^2+y^2-10x-12y+36+25=1

x^2+y^2-10x-12y+61=1

x^2+y^2-10x-12y+60=0

which is the required general form of the equation.

Hence, option A is correct.
