Question

Displacement against time-graph

Independent variable Dependent variable
X-axis y-axis

Time/s Displacement/m
0 20.0
1.0 28.0
2.0 33.0
3.0 45.0
4.0 47.0
5.0 55.0
6.0 63.0
7.0 68.0
8.0 76.0

a) Determine the gradient of the graph.
b) What is the displacement when the time is 2.8s?

Please draw it for me!

Answer 1

a) please find the screenshot of gradient of the graph it is 2nd quadrant.

b)If time is 2.8s then displacement is 40.053

Step-by-step explanation:

• Linear function help in association of two variables.
• formula we use for linear equation is y = mx+c
• Dependent variable is displacement and independent is time.
• We have to find out the displacement if time is the x-axis.
• To find slope m = y2-y1/x2-x1, find the intercept of the line.
• Once you found out intercept it comes to 20.733
• slope comes to 6.9.
• x is the the variable to decided.
• Every linear problem can have an intercept.
• formula found is y = 6.9x +20.733.
