Question

How do you graph `y = 2 - 2x`?

Answer 1

Refer to the explanation.

Explanation:

`y=2-2x` is the same as `y=-2x+2`, which is the slope-intercept form of a linear equation, `y=mx+b`, where `m` is the slope and `b` is the y-intercept. In the given equation, `m=-2` and `b=2`.

In order to graph a linear equation, you need to find at least two points on the graph, plot the points on the graph, then draw a straight line through those points.

To find the points, pick values for `x`, and solve for `y` using the equation `y=-2x+2`.

Point 1
`x=0;` `y=2`

Point 2
`x=1;` `y=0`
