Let "per month" = m
The inequality is
1.5m + 4 ≥ 7
+ 4: Her hair right now is 4 cm long
1.5m: Her hair grows 1.5 per month (m)
≥ 7: She wants it to be at least 7 or more.
1.5m + 4 ≥ 7 is your answer
hope this helps
Transformations:
1.) The -4 moves your y-intercept down 4 units. Without the -4, your y-intercept would be (0,-1)
2.) The -2 in the fraction moves your x-intercept to the to the right 2 units. Without the -2, your x-intercept would be (1/2,0)
