Answer:
1⅓x + y = 9
Step-by-step explanation:
Convert the Standard Form of the given line to Slope-Intercept Form:
- -4y = -3x + 2 [Move -3x to the right side of the equivalence symbol]
- y = ¾x - ½ [Divide everything by -4]
Then, after getting your equation, take the OPPOSITE MULTIPLICATIVE INVERSE of ¾ [perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>(<em>SLOPES</em>)], which is -1⅓ [or -4⁄3]. After getting your slope, you can perform the action with your given ordered pair to find your y-intercept:
1 = -1⅓[6] + b
-8
9 = b
Now that you have your y-intercept, this is your new equation in <em>Slope-Intercept Form</em>:
y = -1⅓x + 9
We are not done just yet. The final step is to convert the Slope-Intercept Form of the line to Standard Form, and here is how it is done:
y = -1⅓x + 9
+1⅓x +1⅓x
--------------
1⅓x + y = 9 → Final equation

A strong positive correlation.
Step-by-step explanation:
The question requires you to calculate the correlation coefficient and then make a conclusion about its value.
Form a table as shown where x is cost of items and y is shipping cost
x y xy x² y²
25 5.99 149.8 625 35.9
45 8.99 404.6 2025 80.8
50 8.99 449.5 2500 80.8
70 10.99 769.3 4900 120.8
190 34.96 1773.2 10050 318.3 ------sum
The formula for correlation coefficient follows;
r=n(∑xy)-(∑x)(∑y) ÷ √{[n∑x²-(x)²] [n∑y²-(y)²]}
where n=4
r=4(1773.2)-(190)(34.96) ÷ √{[4(10050)-190²] [4(318.3)-34.96²]}
r=450÷ √{4100*51)
r=450÷√209100
r=450÷457.3
r=0.98409
The value of r indicates a stronger positive correlation
