4x + y= -9(2,9) write an equation for the line that is parallel to the given line and that contains the given point?

Question

anonymous · Answer

A parallel line has the same slope but different y intercept than the 1st equation. So, 
y = -4x + 9 --- 1st equation rearranged
9 = -4(2) + z ---- 2ns equation where z = y intercept
solve for z 
z = 17

Therefore, the new equation is y = -4x + 17 or 17 = 4x + y

Ok, well $$y=-9-4x$$
so the slope is -4 for that line. So the parallel line must also have the slope -4. Now we have for the second line:

$$y=-4x+b$$

So all we need to do now is solve for b. Luckily we have a point given to us so

$$9=-4(2)+b$$

so b = 17
