Answer: y = -1/2x+7/2.
Step-by-step explanation:
Firstly, we need to understand the formula of point-slope form: y1-y2=m(r1-r2)
Where x and y is the coordinates and m is the slope respectively.
To find the slope:
y1-y2/r1-r2
In this case:
5-4/-3-(-1)=-1/2
We can then put the above slope and the point (-1,4) into the formula:
4-y = -1/2(-1-x)
-y = 1/2+1/2x-4
y = -1/2x+7/2
Alternatively:
y-4=-1/2(x-(-1))
y=-1/2x-1/2+4
y = -1/2x+7/2
