Firstly, we need to understand the formula of point-slope form:
Where x and y is the coordinates and m is the slope respectively.
To find the slope:
In this case:
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
Therefore the answer is y = -1/2x+7/2.
Hope it helps!

Answer:
m∠A=30°
Step-by-step explanation:
we know that
<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross.
Vertical angles always are congruent
In this problem
m∠A=m∠B ----> by vertical angles
we have
m∠A=x
m∠B=3x-60
substitute
Solve for x
therefore
m∠A=30°
