The answer is y=x+2 because you can put it into point slope form
y-4=1(x-2)simplify
y-4=x-2
y=x+2
The slope-intercept form:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
We have the slope [tex]m=1\to y=1x+b=x+b[/tex]
and point (2, 4). Substitute:
[tex]4=2+b[/tex] subtract 2 from both sides
[tex]2=b\to b=2[/tex]
Answer: [tex]y=x+2[/tex]
