Write an equation that represents the line use exact numbers

y = 2/3x +4/3

Step-by-step explanation:

We need two points to find the slope

(1,2) is  one point  (4,4) is another point

m = (y2-y1)/(x2-x1)

m = (4-2)/(4-1)

   = 2/3

The slope is 2/3

We can write the equation in point slope form

y-y1 = m(x-x1)

y-4 = (2/3) (x-4)

Distribute

y-4 = 2/3x - 8/3

Add 4 on each side

y-4+4= 2/3x - 8/3+4

y = 2/3x -8/3+12/3

y = 2/3x +4/3

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
