Answer:
7x + 3y = 44
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Rearrange - 3x + 7y = 5 into this form by adding 3x to both sides
7y = 3x + 5 ( divide all terms by 7 )
y = x + ← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , thus
y = - x + c ← is the partial equation
To find c substitute (5, 3) into the partial equation
3 = - + c ⇒ c = 3 + =
y = - x + ← in slope- intercept form
Multiply through by 3
3y = - 7x + 44 ( add 7x to both sides )
7x + 3y = 44 ← in standard form
So the mode in this would be none since there arent any doubles of any number
I find it's easiest to find the middle of numbers with a simple trick I learned just today!
First, you find out how much the distance is between the two numbers.
0-1-2-3-4-5-6-7
If you count, there is a distance of four in between 3 and 7. So we do the next step.
In the next step, all you need to do is split the distance of the numbers in half. Then we can subtract half fro the bigger number or add the half to the smaller half.
4 / 2 = 2
7 - 2= 5, or 3 + 2 = 5
So the denominator between 1/3 and 2/7 is 0/5. You can add any number you want to the top I think.
