Answer:

y = - 8x - 4

Explanation:

y = mx + b

"m" is slope, "b" is y-intercept.

(
x_(1) ,
y_(1) )

(
x_(2) ,
y_(2) )

m =
(y_(2) -y_(1) )/(x_(2) -x_(1) )

~~~~~~~~~~~~~~~

(0, - 4) are coordinates of y-intercept.

( - 1, 4)

m =
(4 + 4)/(-1-0) = - 8

y = - 8x - 4

Answer:


y=(0)/(-1) -4

Explanation:

first, you have to find the slope, and to do that you use this equation
(y2-y1)/(x2-x1)

so, now to insert your points (0,-4), (-1,4)

(x1,y1) (x2,y2)


(4-4)/(-1-0) = (0)/(-1)

now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4

- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]

therefore, the slope-intercept form is y=
(0)/(-1) -4

[ps, your slope is a zero slope :)]
