Solution:

Given:


y=-7x+4

The equation is the equation of a line in the slope-intercept form.

To get the slope and y-intercept of the equation, we compare it to the equation of a line in slope-intercept form.


\begin{gathered} y=mx+b \\ \text{where;} \\ m\text{ is the slope} \\ b\text{ is the y-intercept} \end{gathered}

Hence,


\begin{gathered} y=mx+b \\ y=-7x+4 \\ \\ \text{Comparing the two equations,} \\ m=-7 \\ b=4 \end{gathered}

Therefore,

The slope is -7

The y-intercept is 4
