i need help finding linear equations! how do you solve them and how do you know if they're linear or not?
PLEASE HELP ME! IM SO CONFUSED!!

Linear equations are generally in the form:
y = mx + b
m = the slope of the line (rise over run); the change in the value of y divided by the change in the value of x between two points on the line.
b = the y intercept; the point at which the line crosses the y axis at which point the value of x is equal to zero. If there is no b as in: y = 2x, then b = zero since y = 2x and y = 2x + b are equal if b = 0.

They're linear if they have x and y terms in them. To solve a linear equation, solve for y. In other words, get y=(whatever the rest of the equation is) Do this by getting like terms and moving things to different sides of the equal sign by addition and subtraction.

Okay...
A linear equation is an equation that when graphed will form a line.
in order to solve them you need the y on one side and the other digits on the left in proper prder. y=mx+b is slope intercept form. then there are more which you could find in a algebra book.

they are linear if there are not 2 points in the same vertical point
