Given that t<span>he
mean lifespan of a sylvania light bulb is 1600 hours with a standard
deviation of 300 hours, an iqr of 450 hours, and a range of 690 hours.
the lifespan distribution is relatively symmetric. 
Since, the distribution is relatively symmetric, the measure of
spread that is the best measurement is the standard deviation.</span>
        
             
        
        
        
<u>(Note: this answer is assuming that the equation has to be put in slope-intercept format.)</u>
Answer:

Step-by-step explanation:
1) Let's use the point-slope formula to determine what the answer would be. To do that though, we would need two things: the slope and a point that the equation would cross through. We already have the point it would cross through, (-3,-4), based on the given information. So, in the next step, let's find the slope. 
2) We know that the slope has to be parallel to the given line,  . Remember that slopes that are parallel have the same slope - so, let's simply take the slope from the given equation. Since it's already in slope-intercept form, we know that the slope then must be
. Remember that slopes that are parallel have the same slope - so, let's simply take the slope from the given equation. Since it's already in slope-intercept form, we know that the slope then must be  .
. 
3) Finally, let's put the slope we found and the x and y values from (-3, -4) into the point-slope formula and solve:

Socratic is a really good app for these type of questions! I definitely recommend. For science too!
