Determine if the point (0,4) is a solution to the sytem of inequalities graphed below. Justify your answer. *** make sure you check the scale here *** the boxes are going up by 2 not by 1 ***

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

Which represents the solution set of the inequality 5x-9 < 21? a. x < 12/5 b. x > 12/5 c. x > 6 d. x < 6

Do,h = (7, 9) (14, 18) the scale factor is
