On Saturday, Tashayla read at least 9 fewer than 4 times as many pages in her book as she did on Friday.How many books did Tashayla read on Friday? Then graph the solution.
+23246 "at least" becomes "≥".
"fewer than" means subtract, so "9 fewer than" becomes "- 9".
y represents the pages read on Saturday.
x represents the pages read on Friday.
y ≥ 4x - 9
Draw the line y = 4x -9 and shade the region above the line to show "at least".
Points that you can use: x = 0 and y = -9 x = 4 and y = 7.
Do you have to be more careful than this? Because, x can't be negative and y can't be negative (you can't read a negative number of pages); do you have to worry about this?
