In order to find the slope, m, you would have to find the change in y over the change in x.
y2 - y1 -12 - 8 -20 -10
---------- = ---------- = ------- = -------- = 5
x2 - x1 6 - 8 -2 -2
The negatives would cancel out and you would get 5 as your slope, which is positive.
Answer:
part A
y = 2x -1
the slope is 2/1 means it will be up 2 right 1 or down 2 left 1 the slope is positive
the y-int is -1
y = 4x -5
the slope is 4/1 means it will be up 4 right 1 or down 4 left 1 the slope is positive
the y-int is -5
part B
the solution to this is (2,3)
Step-by-step explanation:
Answer:
-2, 2, 6
Step-by-step explanation:
f(-4)= -4+2=-2
f(0)=0+2=2
f(4)=4+2=6
Substitute x for the number in parentheses
Answer:
x=1
Step-by-step explanation:
3·(-x) + 3·(-1) = 6·(-1)
-3·x - 3 = -6
3·x = 3
x = 1
Answer:
<em>C. Omitted variable bias
</em>
Step-by-step explanation:
In mathematics and statistics, omitted-variable bias (OVB) happens if one or more important variables is left out by a statistical model.
The bias results in the equation being related to the expected effects of the included variables by the influence of the excluded variables.
