Question 591931
We first solve 8x-4y = -4 for y.



-4y = -8x - 4



y = (-8x - 4)/-4



y = 2x + 1



We now use the point-slope formula and the slope just found.  The slope is the coefficient of x in the equation y = 2x + 1.  The slope is 2.


Let (1,-3) = (a,b)


The point-slope formula is y - b = slope(x - a).


y - (-3) = 2(x - 1)


y + 3 = 2x - 2


y = 2x - 2 - 3


y = 2x - 5


The equation y = 2x - 5 is EXACTLY the same equation given in choice (a).


The answer is choice (a).
