The answer is 3/4.
Step-By-Step Explanation
Slope Formula:m=y2-y1/x2-x1
Substitute: 7-1/9-1
Answer: 3/4
Answer:
1. the range is the biggest number minus the smallest number.
2. for IQR order the data in ascending order, find the median, calculate the median for both the upper and lower halves of the data and the IQR is the difference between the two.
3. MAD is when you find the mean then add all the data values together and divide by the amount of data you have. Lastly, do the data value minus the mean.

Answer:</h2>
First, we need to use <u><em>slope formula*</em></u> to find the slope.
Second, we use the slope we found and <em>ONE</em> of the 2 points listed and plug it into <u><em>slope-intercept form**</em></u> to solve for <u><em>b</em></u>.
Here is what we have so far:
I'm going to use this point:
Here is how to find <em>b</em>:
Finally, we put all of it together and we have our equation.
*Slope formula: <em>m = y₂ - y₁/x₂ - x₁</em>
**Slope-intercept form: <em>y = mx + b</em>
<em></em>
First find the slope, m:
2-(-1) 3
m = -------------- = --------- = 6/7
(1/2)-(-3) 3.5
Now use the slope-intercept formula:
y = mx + b
Choosing the point (1/2, 2), 2 = (6/7)(1/2) + b. Find b (the y-intercept):
14 [ 2 = (6/7)(1/2) + b ] => 28 = 6 + 14b.
Then 22 = 14b, and b = 22/14.
Then the eqn of the line is y = (6/7)X + 22/14
Mult. all terms by 14 to remove the fractions:
14y = 12x + 22
Finally, rearrange the terms: -12x + 14y - 22 = 0. This is the eqn in standard form, as requested.
