Find the slope of the line passing through (-2,5) and (9,-7)?

Marat540 [252]

Use the slope formula.
Y2 - Y1 / X2 - X1
(-7 - 5) / (9 - -2)
(-12) / (11)
So answer: slope(m) = -12/11

Question 3 of 10

Bas_tet [7]

Answer:

A. $y-5=1.5(x-4)$ .

B. $y=1.5x-1$ .

Step-by-step explanation:

The given line passes through (2,2) and (4,5).

The slope the given line can be found using the formula;

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{5-2}{4-2}$

This gives $m=\frac{3}{2}=1.5$ .

The slope-intercept form is $y-y_1=m(x-x_1)$ .

We substitute the second point to get:

$y-5=1.5(x-4)$ .

We expand to get:

$y-5=1.5x-6$ .

$y=1.5x-6+5$ .

$y=1.5x-1$ .

Use the equation below to identify the value fo each variable for the circle.

natita [175]

Answer:

The equation of the circle in standard form is: (x - 2)² + (y - 4)² = 9

Step-by-step explanation:

* Lets revise the standard form of the equation of the circle

- If the center of the circle is point (h , v) and the radius of the

circle is r, then the standard form of the equation of the circle

is (x - h)² + (y - v)² = r²

- (x , y) a general point on the circle

* Lets look to the picture

- The center of the circle is point (2 , 4)

- The highest point on the circle is (2 , 7) and the lowest point

on the circle is (2 , 1)

∴ The diameter of the circle = 7 - 1 = 6

∵ The radius = 1/2 the diameter

∴ The radius of the circle = 1/2 × 6 = 3

* Now we can write the equation of the circle

∵ h = 2 and v = 4

∵ r = 3

∴ (x - 2)² + (y - 4)² = 3²

∴ The equation of the circle in standard form is:

(x - 2)² + (y - 4)² = 9
