.Choose the equation of the line passing through the point (-3, 1) and parallel to y = -x - 4.

y = x + 2

y = -x - 2

y = -x + 4

y = x - 4

Question

.Choose the equation of the line passing through the point (-3, 1) and parallel to y = -x - 4.

 y = x + 2

 y = -x - 2

 y = -x + 4

 y = x - 4

anonymous · Answer

Firstly find the slope of the parallel line given..

anonymous · Answer

y = -x - 4

Compare it with y = mx + c

And tell me what is m here  ??

anonymous · Answer

1º it will have to have the same slope: 
only answers left are: y = -x - 2   and  y = -x + 4
2º check if the point (-3, 1) satisfies the equations above.

anonymous · Answer

i just dont get how to solve it at all :( im horrible at math

anonymous · Answer

This might be easier for you if you use point-slope form instead.
$$y - y_1 = m(x - x_1)$$Remember that slopes of parallel lines are the same. So the slope here is -1. The, remember that $(x_1, y_1)$. So $x_1 = -3$ and that $y_1 = 1$.
$$y - 1 = -1(x - 3)$$$$y = -1(x - 3) + 1$$Can you simplify the right side?

anonymous · Answer

@Calcmathlete there is little mistake I guess..

anonymous · Answer

Oh ok.
$$y - 1 = -1(x + 3)$$$$y = -1(x + 3) + 1$$Can you simplify this?
