Question

Is `y=-x+2` a linear fuction?

Answer 1

Yes.

Explanation:

"Linear" means that the graph or drawing of the function is a straight line. Any equation with a single independent variable (often an 'x') that is not exponential (`x^2, x^3...`) is linear.

Answer 2

Yes.

Explanation:

The slope is not shown, since it is just negative 1 (-1). The y-intercept would be 2.

Answer 3

Yes, the graph is a straight line

Explanation:

Functions that are straight lines are linear.

Since the equation is in slope-intercept form of a linear function, it must be a linear function.

Slope-intercept form: `y=mx+b`
