so confused..."write the equation of a line, in standard form, passing through the point A(-2,7) and parallel to the line whose equation is y=2x-3" ..help please??

Question

anonymous · Answer

parallel lines have the same slope
the slope of $y=mx+b$ is $m$ and therefore the slope of $y=2x-3$ is 2

anonymous · Answer

now you use the point - slope formula 
$$y=y_1=m(x-x_1)$$ with $m=2, x_1=-2,  y_1=7$ make the real number replacements and see what you get

anonymous · Answer

typo there, should have been 
$$y-y_1=m(x-x_1)$$

anonymous · Answer

you get 
$$y-7=2(x-(-2))$$ or 
$$y-7=2(x+2)$$

thank you
