Question

write the equation of the line that has slope2 and that passes through the point (1,3).

Answer 1

slope=m=2
general form of a straight line is: y=mx+c
we hav m=2,x=1 and y=3 we get c=1
therefore equation is y=2x+1.

Answer 2

or u can start from
y-3=2(x-1) Point slope form

Answer 3

2x-y+1=0
