What is the slope of 3x+8y-1=0
Fudgin [204]
One of the most common ways to find the slope is to put the problem in standard, slope-intercept form, which is y=mx+b. The easiest way to describe this process is to isolate y.
Here's how you do it for this problem:
3x+8y-1=0 \\ (3x+8y-1)+1=(0)+1 \\ 3x+8y=1 \\ (3x+8y)-3x=(1)-3x \\ 8y=-3x+1 \\ (8y)/8=(-3x)/8+(1)/8 \\ y= -\frac{3}{8}x+ \frac{1}{8}
Since m is your slope, the answer would be -3/8.
Hope this helps!

A guy-wire is attached from the ground to the top of a pole for support. If the angle of elevation to the pole is 67° and the wi
m_a_m_a [10]
You can solve this problem and calculate the height of the pole, by following the steps below:
 
 Tan(α)=Opposite leg/Adjacent leg
 
 α is the angle of elevation (α=<span>67°).
</span> The opposite leg is <span>the height of the pole. Let's call it "x".
</span> Adjacent leg=137 feet
 
 When you substitute these values into the formula Tan(α)=Opposite leg/Adjacent leg, you have:
 
 Tan(α)=Opposite leg/Adjacent leg
 Tan(67°)=x/137
 
 You must clear the "x"
 
 x=137xTan(67°)
 x=322.75
 
 W<span>hat is the height of the pole?</span> 
 
 The answer is: The height of the pole is 322.75 feet.
