Question

What is the slope-intercept form of the function that contains the point (–1, 5) and has a slope of –4?



y = __ x + __

Answer 1

slope intercept form of a line with slope \(\color{red}{m}\) and y intercept of \(\color{blue}{b}\) :
\[\large y =\color{red}{m} x + \color{blue}{b} \]

Answer 2

you're given slope = -4 so you already know that \(\color{red}{m=4}\)

Answer 3

you just need to find the y intercept \(\color{blue}{b}\)

Answer 4

how do i do that ?

Answer 5

he means m = -4

to find \(b\) use the given point (-1,5)

let x = -1, y=5

then

y=-4x+b becomes 5=-4(-1)+b

Answer 6

what is b?
