It doesn’t make any difference whether or not the data is grouped, the mean is the same. So b. false.
Draw y = -1/2x + 4 on the graph because it’s already converted into y = mx + b form. And then for the other one you get y = 1/4x + 1 and you have to graph that too! Remember rise over run too, but idk if your teacher taught you that.
Step-by-step explanation:
To find the slope of any linear line you would have to use the formula
.
(-6 , 1) = (
,
)
(0 , 3) = (
,
)
Now you would insert the values into the formula....
=
= 
1/3 is your answer.
If you want to check your answer, you would use the formula mx + b= y
m= slope
x = the x-coordinate in either of the coordinates
b= the y-intercept
y = the y-coordinate of the coordinate you chose
mx +b =
(-6) +3 = -2 +3 = 1
1/3 is the correct answer
Hope this helps!!!
