First: make a graph, then set the x-axis as age (the horizontal line) and hours of watching tv on the y-axis (the vertical line). Then put in the data. The for question b: if the dots form a rough line, then it’s linear. Then for c: draw a line that is roughly what all the dots represent. Then (also for d) read off of that line.
Answer:
(7,6)
Step-by-step explanation:
A forumula you can use is
y2 - y1
---------
x2 - x1
So take 5 - (-2) which equals 7
Then take 7 - 1 which equals 6
so you get 7/6 or (7,6)
Answer:
y = 9
Step-by-step explanation:
the equation of a horizontal line parallel to the x-axis is
y = c
where c is the value of the y-coordinate the line passes through
the line passes through (15, 9) and (- 2, 9)
both points have y-coordinate of 9, hence
y = 9 ← is the equation of the line
