What is the slope of the line that passes through the points A(-2,3) and B(-12,6)?

harina [27]

Answer:

The answer is

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(-2,3) and B(-12,6)

The slope is

$m = \frac{ 6 - 3}{ - 12 - - 2} = \frac{3}{ - 12 + 2} \\ = - \frac{3}{10}$

We have the final answer as

$- \frac{3}{10}$

Hope this helps you

Determine the rate of change of the following linear equation as it translates from (-5, -1) to any other point on the line.

anzhelika [568]

The rate of change of the linear equation is $-\frac{2}{3}$

Explanation:

The given two coordinates are $(-5,-1)$ and $(1,-5)$

To determine the rate of change, let us use the formula,

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

Substituting the coordinates in the equation, we get,

$m=\frac{-5+1}{1+5}$

Simplifying, we have,

$m=\frac{-4}{6}$

Dividing, we get,

$m=-\frac{2}{3}$

Thus, the rate of change of the linear equation is $-\frac{2}{3}$
