See explanation.

Explanation:

To graph a line given as $y = a x + b$ $y=ax+b$ you can substitute 2 different values for $x$ $x$ to calculate the corresponding values of $y$ $y$ .

$f (0) = - 4 \cdot 0 + 4 = 4$ $f(0)=-4*0+4=4$

$f (1) = - 4 \cdot 1 + 4 = 0$ $f(1)=-4*1+4=0$

Final step is to draw a line passing through the calculated points: $(0, 4)$ $(0,4)$ and $(1, 0)$ $(1,0)$ .

Explanation:

$one way is to find the x and y intercepts, that is where$ $"one way is to find the x and y intercepts, that is where"$
$the line crosses the axes$ $"the line crosses the axes"$

$∙ let x = 0, in the equation for y-intercept$ $• " let x = 0, in the equation for y-intercept"$

$∙ let y = 0, in the equation for x-intercept$ $• " let y = 0, in the equation for x-intercept"$

$x = 0 \to y = 0 + 4 = 4 \leftarrow y-intercept$ $x=0toy=0+4=4larrcolor(red)" y-intercept"$

$y = 0 \to - 4 x + 4 = 0 \to x = 1 \leftarrow x-intercept$ $y=0to-4x+4=0tox=1larrcolor(red)" x-intercept"$

$plot the points (0, 4), (1, 0) and draw a straight line$ $"plot the points "(0,4),(1,0)" and draw a straight line"$
