Answer:
Folow these steps:
find the slope:
equation for slope: y2-y1 / x2- x1
4-2 / 4-1
2/3 is the slope
y=mx+b
y=2/3x+b
Now just plug in the x and y of either point into the equation. IM using (1, 2)
2=2/3(1)+b
2=2/3+b
b=1 1/3
Now that we have the y intercept and slope, construct the equation:
y=2/3x+1 1/3
