- 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>
If you mean just any fraction in the world that isn't equivalent to 1/3, then 5/6 7/9 and 2/10 would work
Hope this helps! Good Luck!
Answer:
Step-by-step explanation:
Let x = number of hours to pull weed in a day
Let y = number of hours to now lawn in a day
It takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the lawn. She can work no more than 8 hours a day.
This means
3x + 2.5y is lesser than/ equal to 8
She charges $50 to weed and $65 to mow the lawn.
This means she charges
50x +65y
She needs to cover her expenses of $120 to make a profit. This means she needs to earn an amount greater than or equal to $120
50x + 65y greater than or equal to 120

➷ To find the median, you need to order your numbers first.
14, 16, 18, 21, 34, 60
There is an even amount of numbers, so you find the mean of the middle two numbers.
18+21=39/2=19.5
Median=19.5

To solve these questions, use this formula:
X3= F(X1-X2)
Y3= F(Y1-Y2)
Where X3 is the X value in the coordinate your solving for, F is the fraction, X1 is the first X and X2 is the second X
Plug in your numbers to fit this:
X3= 1/4 x (0--2)
Y3= 1/4 x (4- -3)
By solving you get:
(-.5, 1.75)
