1(a)[1]
Point (6.2, 162) plotted correctly [1]
Horizontally 6.15 < point < 6.25 Vertically 160 < point < 164
1(b)[1]
Positive [1]
Ignore embellishments, e.g. strong, etc. Condone +ve but not + alone.
1(c)[1]
Ruled line of best fit drawn [1]
Line of best fit must pass between (4.35, 116) and (4.35, 134) and between (6.5, 158) and (6.5, 176). Condone very good freehand.
1(d)[1]
Reading at 140 from their straight line with positive gradient [1]
Strict FT their straight line with Tolerance strictly less than ±1 square which means lobf value –0.05 < answer < lobf value + 0.05, positive gradient e.g. do not allow an answer of 5.1 if their reading should be 5.05 which is a misinterpretation of the scale.
