“week 14” in math 10
In this week of math 10 we learned about equations such as general form.
In this blog post I will teach you how to find the slope of an equation without graphing.
For starters you need two coordinates for this example lets use (-1, 2) and (2, 3)
The formula we will be using for this question is.
[m] is slope.
The first step to solving the equation is to understand the equation.
The first thing you might notice is the Y and the 2 what that is asking you to do is take the Y coordinate from the second coordinate group. and place it on the top.
Now repeat that on the bottom with the X coordinate from the second coordinate group.
The first part of the equation should be 3 over 2.
Now lets do the next part.
The next part is slightly more challenging as you need to keep track of the subtraction symbol.
now lets do the Y coordinate.
All we have to do is place the y coordinate from the first set of coordinates in the spot marked with y1
For the next part we need to take the X from the first equation, but alas it is a negative. Don’t give up yet for there is a solution, do you know that 2 negative make a positive. (helpfully you do)
All you need to do is change the negative into a positive.
Making our final equation:
3 – 2 over 2 + 1
Solving the equation we are given a slope of 1 over 3
I hope you better understand hope to find the slope of an equation without graphing. If you don’t, feel free to leave a comment and I will get to you when I can.
I apologize for this being a shorter blog post than usual but I have must to do this weekend.
