how do i solve this:

y = -2x +4

Mathematics

Noting to "solve" here, since you have 2 unknowns there would be an infinite number of solutions.

What can you do with it?
- perhaps graph it, by ...

sub in any x you feel like
e.g. let x = 3, then y = -2) ---> point (3,-2)
let x = 0 , then y = 4 ---------> point (0,4)
let x = 45.78, then y = -87.56 --> point (45.78, -87.56)
etc. to infinity

To solve the equation y = -2x + 4, you need to find the value of x when y is given or find the value of y when x is given.

To find the value of y when x is given, substitute the given value of x into the equation and solve for y. For example, if x = 2, you would substitute x = 2 into the equation and solve for y as follows:

y = -2(2) + 4
y = -4 + 4
y = 0

So, when x = 2, y = 0.

To find the value of x when y is given, substitute the given value of y into the equation and solve for x. For example, if y = 6, you would substitute y = 6 into the equation and solve for x as follows:

6 = -2x + 4
2x = 6 - 4
2x = 2
x = 1

So, when y = 6, x = 1.

You can use this process to solve the equation for any given values of x or y.
