Question

Slope intercept form of points 0, -4 and -1, 4

Answer 1

Answer:

$y=\frac{0}{-1} -4$

Step-by-step explanation:

first, you have to find the slope, and to do that you use this equation $\frac{y2-y1}{x2-x1}$

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

                                                      (x1,y1)  (x2,y2)

$\frac{4-4}{-1-0} = \frac{0}{-1}$

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=$\frac{0}{-1}$ -4

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

Answer 2

Answer:

y = - 8x - 4

Step-by-step explanation:

y = mx + b

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

( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

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

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

( - 1, 4)

m = $\frac{4 + 4}{-1-0}$ = - 8

y = - 8x - 4
