Answer:
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
