Do we need to draw triangles on the graph to find out the gradient of the best fit and the worst acceptable lines ? Please someone reply asap ! Thanks in advance !
sis which component???
value of gradient is that of best fitPLZ HELP ME ON HOW TO CALCULATE GRADIENT WITH ERROR?
calculate gradient of worst line and use formula: gradient of best fit - gradient of worst line=uncertainityPLZ HELP ME ON HOW TO CALCULATE GRADIENT WITH ERROR?

Use the gradient of best fit to calculate y-intercept and then use worst acceptable gradient to calculate y-intercept.The difference of these y-intercepts is the error of the constant.
not sure abt the first one. but i think that depends on the values given.
if the values given are in decimal points, then the calculated value shud have the same no. of decimal points.
and if it is not in decimal points, then the calculated value shud be in the same no. of sig fig.
2) yes the error shud have the same no of decimal points/sig fig.
3)that depends on the values u have taken.
Hope i helped.

if you ve taken your coordinates to 3 sf then should nt your gradient be to 3 or 4 sf?? do correct me if i m wrongAlhamdullilah!! I am able to solve the question u mentioned. I checked it from mark scheme also and found everything correct. Hope it vl help u View attachment 28292View attachment 28293View attachment 28294View attachment 28295View attachment 28296
