We have to find the slope and the y-intercept of the linear function shown.

For doing so, we will take two points that pass through the line and we will use the formula:


m=\frac{y_2-y_1}{x_2-x_1_{}_{}}

for finding the slope. In this case, two of those points could be:


\begin{gathered} (4,0) \\ (0,3) \end{gathered}

Using them, and replacing onto the slope formula we get:


m=(0-3)/(4-0)=-(3)/(4)

This is, the slope is - 3/4.

For the y-intercept, we see that the function passes through the point:


(0,3)

and then, when x=0, y=3. This means that the y-intercept is 3.
