Answer:
Part 1: m = -7
Part 2: y = -7x -11
Part 3: 7x + y = -11
Step-by-step explanation:
Part 1
Select 2 points, in this case (-2, 3) and (-1, -4) and then use the slope formula
m = (y2 - y1) / (x2 - x1)
m = (-4 -3) / (-1 - -2) =
m = -7/1
m = -7
Part 2
Use the point-slope form equation to find the slope-intercept form
y - y1 = m(x - x1)
y - 3 = -7(x - -2)
y = -7(x +2) +3
y = -7x -14 +3
y = -7x -11
Part 3
Move the x and y to the same side of the equation
y = -7x -11
7x + y = -11

Answer:
2000
Step-by-step explanation:
Expanded form:
80 × (20 + 5)
Partial products:
80 × 20 = 1600
80 × 5 = 400
Sum of partial products: 1600 + 400 = 2000.
Answer:
1.9
Step-by-step explanation:
The MAD is found by <em>finding the mean, then finding how far each number is to the mean, then finding the mean of that.</em>
The mean is: <em>(1 + 8 + 3 + 1 + 3 + 3 + 7 + 5 + 1 + 3)/10</em> = 35/10 = <em>3.5</em>
The distances of all of the numbers is <em>(absolute value of the difference between 3.5 and the number) </em>: <em>2.5, 4.5, 0.5, 2.5, 0.5, 0.5, 3.5, 1.5, 2.5, 0.5</em>
The mean of those is: <em>(2.5 + 4.5 + 0.5 + 2.5 + 0.5 + 0.5 + 3.5 + 1.5 + 2.5 + 0.5) /10</em> = 19/10 = 1.9
