Answer

The slope and y-intercept of the given equation $f\left( x \right)=-4x+5$ of the line is -4 and 5

Work Step by Step

Consider the equation of the line $f\left( x \right)=-4x+5$. Comparing the given equation with the general slope-intercept form: $y=mx+c$ Slope $=-4$ Now, to find the y-intercept, put $x=0$ in the given equation: $\begin{align} & y=-4\left( 0 \right)+5 \\ & y=5. \end{align}$
