We are given the following two points

(-4, 0) and (-5, -3)

The slope is given by

m=\frac{y_2-y_1}{x_2-x_1}\text{where }(x_1,y_1)=(-4,0)\; \text{and  }(x_2,y_2)=(-5,-3)

Let us substitute the given values into the slope formula

m=\frac{y_2-y_1}{x_2-x_1}=\frac{-3-0}{-5-(-4)}=\frac{-3}{-5+4}=\frac{-3}{-1}=3

Therefore, the slope of the line is 3

Which equation results from taking the square root of both sides of (x 9)2 = 25? x 3 = ±5 x 3 = ±25 x 9 = ±5 x 9 = ±25.
kow [346]

The equation which is results from taking the square root of both sides of the provided equation is,

(x+9)=\pm5\\

<h3>What is the square root?</h3>

A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.

Let a number is <em>a. </em>Then this number in the form of square root can be written as,

a=\sqrt{a}\times \sqrt{a}

The given algebraic equation in the problem is,

(x+ 9)^2 = 25

Take the square root, in both sides,

\sqrt{(x+ 9)^2} = \sqrt{25}\\\sqrt{(x+ 9)^2} = \sqrt{5^2}

Cancel out the square root with the square of the number as,

(x+9)=\pm5\\

Hence, the equation which is results from taking the square root of both sides of the provided equation is,

(x+9)=\pm5\\
