Slope formula: (y² - y¹) / (x² - x¹)

(2, 5) and (8, -4)

x¹ = 2

x² = 8

y¹ = 5

y² = -4

-4 - 5 = -9

8 - 2 = 6

Answer: -9/6

Hope this Helps!!

Slope is =y2-y1/x2-x1
So
= - 4 - 5/ 8-2
= - 9/6
= - 3 / 2 this the answer

PSYCHO15rus [73]

Your graph should look something like the one below, an exponential function (this is because your are raising a number to the power of x.

Find the equation of a circle with a point at ( 10 , - 4 ) and a point at ( -2 , - 4 )

astra-53 [7]

Answer:

Solution given:

letA=(10,-4)

B=(-2,-4)

centre[C](h,k)= $\frac{10-2}{2},\frac{-4-4}{2}=(+4,-4)$

radius= $\sqrt{(4-10)²+(-4+4)²}=6$ units

we have

Equation of a circle is;

(x-h)²+(y-k)²=r²

(x-4)²+(y+4)²=36

or.

x²-8x+16+y²+8y+16=36

x²-8x+8y+y²=36-32

x²-8x+8y+y²=4

The equation is (x-4)²+(y+4)²=36 or x²-8x+8y+y²=4.

Which of the following best describes the slope of the line graph below

vlada-n [284]

The answer would be 0, as the slope of a line is definite as it pitch, or rate of increase. So if the line were going up to the right it would be positive, to the left, negative. An undefined slope would be the exact opposite of that slope. The slope you have, when written in y=mx+b is y=4
