**Graph the equation. Tell whether the equation is a function.**** **

$y=-5x+2$

The equation $y=-5x+2$ is **a function**.

The given equation is $y=-5x+2$.

We can see that our given equation is in slope-intercept form $y=mx+b$, where *m* represents slope of line and *b* represents the *y*-intercept.

Upon looking at our given equation, we can see that the slope of our given line is $-5$ and the *y*-intercept is at point $\left(0,2\right)$.

Upon graphing $y=-5x+2$, we will get our required graph as shown below:

We can see that no vertical line will intersect the graph of equation $y=-5x+2$ more than one place that is each *x* value corresponds to a specific *y*-value.

Therefore, the equation $y=-5x+2$ is a function.

The given equation is a function.
