- Slope-Intercept Form: y = mx+b, with m = slope and b = y-intercept
So perpendicular lines have <u>slopes that are negative reciprocals</u> to each other, but firstly we need to find the slope of the original equation. The easiest method to find it is to convert this standard form into slope-intercept.
Firstly, subtract 3x on both sides of the equation: 
Next, divide both sides by -4 and your slope-intercept form of the original equation is 
Now looking at this equation, we see that the slope is 3/4. Now since our new line is perpendicular, this means that <em>its slope is -4/3.</em>
Now that we have the slope, plug that into the m variable and plug in (-4,-5) into the x and y coordinates to solve for the b variable as such:
<u>In short, your new equation is y = -4/3x - 10 1/3.</u>
Answer:
17.5 yds =r
Step-by-step explanation:
Circumference is given by
C = 2*pi*r
35pi = 2 *pi*r
Divide each side by 2pi
35pi/2pi = 2*pi*r/2pi
17.5 =r
Answer:
non linear

Answer:
1. 3
Step-by-step explanation:
For the first one, you have to follow m(slope)=y2-y1/x2-x1.
So in this case for the first one, it's 4-(-2)/3-(1) which is 3.
Answer:
x=12
Step-by-step explanation:
We know that a right angle is 90 degrees. So we can make the equation 
Now, we can solve fore X! We can combine 35 and 7 to make the equation 
. In order to isolate x we have to subtract 42 from both sides, getting us the equation 
Now, in order to isolate x we must divide each side by 4, getting us the equation 
. To prove that x=12, we can subsitute x for 12. This means that we can do 
which simplified, is 90=90, making x=12 true. Hope this helps :)
