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

Question

compassionate · Answer

Lines that are parallel have the same slope. We're given the points -3 and 1.

By this information, you can use y = mx + b
x = -3 
x = 1 

Since we want it to be parallel to the equation y = -x - 4 
We know the slope of the new equation we're looking for will be -x

ok...

compassionate · Answer

Do you understand?

anonymous · Answer

no.. i thought it would be y= -x+4

Choose the equation of the line passing through the point (-3, 1) and parallel to y = -x - 4. 


Give points: $$(-3, 1)$$

Given equation of paralleled: 
$$y = -x - 4$$

anonymous · Answer

makes sense but its not one of my options...

anonymous · Answer

y = x + 2 

y = -x - 2 

y = -x + 4 

y = x - 4

anonymous · Answer

those are my options..

compassionate · Answer

$$1 = -1(-3) + b$$
$$1 = 3 + b$$
$$-2 = b$$

Now we plug in the -2 into the slope-intercept form. 
$$y = mx + b$$
$$y = -x - 2$$
