What is the y-intercept of the function f(x)=4 – 5x?
schepotkina [342]
The slope-intercept form of a line is
y=mx+b
where m is the slope
b is the y-intercept

if you convert the function into an equation, then
y=4-5x

rearranging the equation
y=-5x +4
thus
m=-5 and b=4

the y-intercept of the function is 4
