Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form. a) y – 1 = 2(x – 3) b) y – 3 = 2(x – 1) c) x – 1 = 2(y – 3) d) x – 3 = 2(y – 1)

So point slope form is y=mx+b where m=slope and b=y intercept so

in (x,y) form
one solution is x=1 and y=3, also slope is 2 so
m=2
subsitute
3=2(1)+b
3=2+b
subtract 2
1=b
equation is
y=2x+1

tricky answers so simplify them
A: y-1=2(x-3)
distribute
y-1=2x-6
add 1
y=2x-5
not the answer

B: y-3=2(x-1)
distribute
y-3=2x-2
add 3
y=2x+1
correct
the answer is B
