Question

A line contains the points (4,4) and (5,2). What is the equation of the line

Answer 1

Answer:y=-2/1x+12

Step-by-step explanation:

To find slope you need to use slope formula (y2-y1)/(x2-x1)

(2-4)/(5-4)

-2/1 is our slope

Now we need the y-int

Y=-2/1x+b

Take one of the given points and apply it to our equation

2=-2/1(5)+b

2=-10/1+b

2=-10+b

Add 10 to each side

12=b

Our final equation is

y=-2/1x+12
