Answer:
Step-by-step explanation:
first, you have to find the slope, and to do that you use this equation
so, now to insert your points (0,-4), (-1,4)
(x1,y1) (x2,y2)
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= -4
[ps, your slope is a zero slope :)]
