Question

Write an equation in point-slope form of the line that passes through the point (4, 7) and has a slope of -1

Answer 1

Answer: y=-x+11

Step-by-step explanation:

y=mx+b

Since we already have the m (slope) we can just add it to our equation, so,

y=-x+b

Now, we plug in (4,7) and solve for b

7=-1(4)+b

b=11

Now we put it all together

y=-x+11

Answer 2

Straight Answer:

y-7=-1(x-4)
