Answer: A. m=-4
Step-by-step explanation:
Answer:
<h2>x - 4y = 8</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
<em>m</em><em> - slope</em>
The formula of a slope:
============================================
We have the points (-4, -3) and (12, 1).
Substitute:
Put the volume of a slope and the coordinates of the point (12, 1) to the equation of a line:
The standard formula of an equation of a line:
Convert:
<em>multiply both sides by 4</em>
<em>add 4 to both sides</em>
<em>subtract x from both sides</em>
<em>change the signs</em>
If you are asking about CIE EXAMS they didn’t say anything about cancelling it
$0.50, because if you divide 4.0 by 8 you get .5.
