I believe the answer is: By using the point slope formula, which states that a given point (x1, y1) and a slope m, the equation of the line can be written as y - y1 = m(x - x1)
To find the mean, add up at the numbers and divide by the number of numbers in the set (6)
9 + 4 + 7 + 3 + 10 + 9 =
9 + 11 + 12 + 10
20 + 22
42
42 / 6 = 7
the mean is 7.
!) $18,000
<span>2) 1000 + 425(48) = $21,400 </span>
<span>3) 21,400 - 18,000 = $3400 </span>
<span>4) $23,500 </span>
<span>5) 2000 + 60(425) = $27,500 </span>
<span>6) 27,500 - 23,500 = $4000</span>
First, you plug your given values in. Since x is 1.5, it will be multiples by 2x to get 3.2. Since y is -3, it will be added to 1 to get -2. Finally, the two are multiplied together to get -6.4 if I am correct.
