Determine the equation of the line between the coordinates: (-2,-5) and (-4,-2)
Question
Answer:
To find the equation of the line passing through the coordinates (-2, -5) and (-4, -2), we'll use the point-slope form of a linear equation:
$$ y-y_1=\:m\left(x-x_1\right) $$
Given the points, we can calculate the slope m:
$$ m=\frac{y_2-y_1}{x_2-x_1} $$
$$ m=\frac{-2-(-5)}{-4-\left(-2\right)}=\frac{3}{-2}=\:-\frac{3}{2} $$
Now, we can choose either point to plug into the point-slope form. Let's use (β2,β5) as the point:
y-(-5) = -3/2 (x -(-2)),
y + 5 = -3/2 (x + 2)
Now, let's distribute the slope:
y + 5 = -3/2x - 3
Subtract 5 from both sides:
y = -3/2x - 3 - 5
y = -3/2x - 8
So, the equation of the line passing through the coordinates (-2, -5) and (-4, -2) is:
y = -3/2x - 8
