Write the equation of the line that passes through (4,2) and is parallel to the line y=2x-1

Question

slaaibak · Answer

Use this formula:

y - y1 = m(x - x1)

you know that parallel lines have the same slope, so you have m.

anonymous · Answer

you got that?

anonymous · Answer

$$y=2x-1$$ looks like 
$$y=mx+b$$ with  
$$m=2,b=-1$$ so you know the slope of your line is 
$$m=2$$

anonymous · Answer

then write 
$$y-2=2(x-1)$$ and solve for by first using the distributive property on the right and then adding 2 to both sides

anonymous · Answer

so 2x-y=?

anonymous · Answer

$$y-2=2x-2$$
$$y=2x$$ or if you prefer 
$$2x-y=0$$

slaaibak · Answer

satellite, don't you mean

y - 2 = 2(x - 4)

y - 2 = 2x - 8

y=2x - 6
