We first rewrite the first equation in slope-intercept form.

(A) This is quite easy: subtract 2x from both sides:
y=−2x+7 so the slope is −2

(B) If two lines are perpendicular, multiplying their slopes will allways give a result of −1. Let's call the slope we want to find m
The equation is allready in slope-intercept form with a slope of 10.

So: m 10 = - 1 m = - 1 10

Find the slope of line parallel to 2y=6x+8
asked 2022-07-02
For what values of k in this set of linear equations A x = b has no solutions, an infinite number of solutions and a unique solutions?
I know I want to be using Gaussian Elimination here, I've augmented the matrix and I'm perfectly familiar with ERO's and back-solving for systems without unknown constants but this is new to me.
2 2 0 2 0 k 1 1 1 2 k 2
Would I try to be putting this into Row-Echelon form? I have an inkling by playing with it that k = 1 for no solutions and k = 1 for an infinite number of solutions. I can't do the Gaussian steps properly with a k involved to produce some decent working though.
Thank you in advance for any help, solutions or tips. :)

Find the slope of a line that is perpendicular to the graph of : y= -1/2x + 4
asked 2022-06-27
One thing I've hated about differential equations is how I need to guess the form of the solution.
e.g. it's easy to show that solutions to a linear constant-coefficient differential equation such as
y + 2 y + 3 y + 4 y = 0
have the form of (some linear combination of) exponentials:
You can just plug in y = e a x + b and show that the equation is satisfiable.
But I feel there is something wrong if I must find the solutions through guess-and-check.
Yet what I was never told, and what I seem to never be able to find from looking online, is how to derive this fact rigorously, when I don't already have the intuition necessary to guess the form of the solution?
Sitting down and working through some math, I've come up with some nonsense that works quite beautifully:
1. Place the homogeneous equation into the following matrix form:
y = A y
where, for example, we have y = [ y y ] T
2. Drop the arrows and pretend everything is a scalar:
y = A y
3. Separate the, uh, variables:
d y d x = A y
d y y = A d x
4. Integrate:
d y y = A d x
ln y = A x + b
y = e A x + b
5. Profit!
How do I derive it properly?

This question from linear algebra
Suppose you [ have a consistent system of linear equations, with coefficients in R, which are homogeneous - that is, all the bi are 0. Explain why the set of solutions to this system forms a vector space over R. Then, explain why if the system was not homogeneous (i.e. if at least one of the bi is nonzero) the set of solutions would definitely NOT form a vector space over R.
Who knows?
