Answer:
y=-5/2x-1
Step-by-step explanation:
We can just use two of the points to find the equation
I am going to use (0,-1) And (-2,4)
Slope = y2-y1/x2-x1
Which is
4+1/-2+0
This can result in
-5/2
Thus the slope is -5/2
Now the equation looks like this in slop intercept form:
y=-5/2x+b
We need to find b or the y-intercept so we use one of the points to substitute our x and y.
I am going to use (0,-1)
Which is
-1=b
Thus b is -1
The equation is
y=-5/2x-1
Hope this helps!
