Answer:
A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables
Step-by-step explanation:
In many real-life situations, scatter plots follow patterns that are approximately linear. If y tends to increase as x increases, then the paired data are said to be a positive correlation.
Do you have any answer choices if you do could you add them
Answer:
x=100
Step-by-step explanation:
Simply multiply the 1/5 by 20 to get x, since 5*20, you get 100.
Answer:
-1/2
Step-by-step explanation:
We can find the slope if we are given two points
m = (y2-y1)/(x2-x1)
= (4-8)/(4 - -4)
= (4-8)/ (4+4)
= -4/8
= -1/2
