Give us the whole equation, and we can help.
no.
A linear equation is the equation of a line and that consists of an infnite number of points. What you have, in x = -4 and y = -1/3, is a single point. A single point is not a line and so there cannot be a linear equation (suitable for a line) to represent a point.
there's no equals sign so it's not an equation, it's an expression. i assume you mean (a^2)/(b^8) in which case it's a non-linear expression in both a and b. "linear in x" means the highest power of x in the expression is 1. this means there is no x^2 or x^8 etc. 2x + 4 is linear because the highest power of x is 1 2(x^3) + 4x + 7 is nonlinear because the highest power of x is 3
rise over run.
Slope= rise over run
No, it is not.
Yes. In other words, the equation is y=(10-1)/4x or y=5/2x -1/4
Yes, 3x+4y=10 is a linear equation, because you can move the x over to the other side, and divide by 4 to get y=-3/4x+5/2. Generally, any equation in the form ax+by=c is a linear equation.
the linear relationship is up four over one.
It is an incorrect equation.
The ratio of rise over run is known as slope. In a linear equation, it can be found by identifying m in the equation Y=mx+b
The most general form of a linear equation, in n-dimentional space, is y = sum(mixi) + c where the summation is over i = 1,2,3,...,n-1 The simpler (2-dimensional) version of the linear equation is y = mx + c where m is the slope and c is the y-intercept.
