i have this question from my year 11 maths B assignment that i do not completely know how to solve.. i was wondering if i could get some help thankyou..
the equation of line of best fit was:
y=.00007x - 0.0006x - 0.04x + 0.7164x + 0.3863
what do i do with this equation?
For example if I said make a best fit line for this chart
y|1 2 4 4.2
x|1 2 3 4
You can see this closely resembles the line y=x...so this takes the points and makes a curve/function that "best fits" the data points
oh ok i think i get it now. thankyou for helping me, much appreciated! so if i was given 2 equations of the line of best fit for 2 different sets of data, wat do i need to do with them, do i put them into a graph or do i just leave them? on the assignment it hasnt got anything to tell me what i have to do with them.
