Given the Linear Equation:


y=-5x+2

You can find the y-intercept and the x-intercept in order to graph it.

Notice that it is written in Slope-Intercept Form:


y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

In this case, you can identify that the y-intercept is:


b=2

In order to find the x-intercept, you need to substitute this value of "y" into the equation:


y=0

Because the value of "y" is zero when the line intersects the x-axis.

Then, substituting that value and solving for "x", you get:


\begin{gathered} y=-5x+2 \\ 0=-5x+2 \\ -2=-5x \\ \\ (-2)/(-5)=x \\ \\ x=0.4 \end{gathered}

Now that you know that the line passes through these points:


(0.4,0),(0,2)

You can plot them on the Coordinate Plane. See the picture below:

Finally, draw the line passing through those points.

Hence. the answer is:
