Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2) and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)
Answer:
22 ft by 18 ft
Step-by-step explanation:
Area = l * w
Area = (x+8) * (x+4) = x^2 +12x+32
396 = x^2 +12x+32
400 = (x+6)^2
20 = x+6
x = 14
x+8 = 22
x+4 = 18

Answer:
36
Step-by-step explanation:
36
The equation of the line of best fit of a scatter plot is y = -8x + 3.
This equation is in slope-intercept form, or y = mx + b, where m is the slope and b is the y intercept.
Thus, the y intercept in this equation is 3.
