What should larmont do to write a correct point slope equation for this line? (-8,5) and (-5,7)

Ronch [10]

ANSWER

Therefore the correct answer is B

EXPLANATION

The equation in the point slope form of a straight line is given by the formula;

$y-y_1=m(x-x_1)$ , where $m$ is the slope and the point $(x_1,y_1)$ is any point on the line.

Since two points on the line are given, Lamont must find the slope using the points $(-8,5)$ and $(-5,7)$ as follows;

$m=\frac{7-5}{-5--8} =\frac{7-5}{-5+8} =\frac{2}{3}$ .

He can now choose one of the points as $(x_1,y_1)$ .

If he uses $(-8,5)$ , the he obtains,

$y-5=\frac{2}{3}(x--8)$

Which gives $y-5=\frac{2}{3}(x+8)$ as the equation of the line.

Therefore the correct answer is B

A(4,-7) B(-2,1) find AB

Natali5045456 [20]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\A(\stackrel{x_1}{4}~,~\stackrel{y_1}{-7})\qquadB(\stackrel{x_2}{-2}~,~\stackrel{y_2}{1})\qquad \qquadd = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}\\\\\\AB=\sqrt{[-2-4]^2+[1-(-7)]^2}\implies AB=\sqrt{(-2-4)^2+(1+7)^2}\\\\\\AB=\sqrt{(-6)^2+8^2}\implies AB=\sqrt{36+64}\implies AB=\sqrt{100}\implies AB=10$
