Answer:

y=-\frac{2}{3}x+6

Step-by-step explanation:

we have been give  that

slope, m = -2/3

The line passes through the point (-3,8).

Hence, x_1=-3,y_1=8

The point slope form of a line is

y-y_1=m(x-x_1)

Substituting the known values

y-8=-\frac{2}{3}(x-(-3))

On simplifying, we get

y-8=-\frac{2}{3}x-2\\\\y=-\frac{2}{3}x+6

Thus, equation of line is y=-\frac{2}{3}x+6

Round 4265 to the nearest hundred
Hatshy [7]
Answer:

4300

Explanation:

The given number is 4265

This can be written as:

4 thousand

2 hundred

6 tens

5 units

Therefore, since 6 is greater than 5, change 6 and 5 to zero and 1 to 2.

4265 rounded to the nearest hundred becomes 4300

Find the standard form of the equation of the circle with endpoints of a diameter at the points (9,2) and (-7.4).
kicyunya [14]

Answer:

(x-1)²+(y-3)²=65

Step-by-step explanation:

the common view of the equation of a circle is:

a) (x-a)²+(y-b)²=r², where (a;b) - the centre of the required circle, r - the radius of the required circle;

b) using the coordinates of the endpoint of the given diameter it is possible to calculate the coordinates of the centre of the required circle and its radius²:

the coordinate x of the required circle is: (9-7)/2=1;

the coordinate y of the required circle is: (2+4)/2=3.

the radius² of the required circle is:

r²=0.25*[(9- -7)²+(2-4)²]=0.25*260=65.

c) after the substitution the values of 'a'; 'b' and 'r²' into the common equation of the circle:

(x-1)²+(y-3)²=65.

PS. additional: the given points (9;2) and (-7;4) belong to the final equation, if to substitute their coordinates into it.

The suggested way of solution is not the only one.
