Rocky pays a flat rate of $5 per month plus $0.10 per minute for his long-distance phone plan. He wants his total monthly bill to be less than $20.
Do you know how to write a linear equation, or an inequality?
No
Do you know what a linear equation is supposed to mean?
No.
The form y=mx+b is the slope-intercept form. Where m is the slope, which is rise over run between two points. And b is the y-intercept, the coordinate point where the line crosses the y-axis. Agreed?
For this question, does the teacher just want you to write the inequality out?
Well, you went offline. But, the steady rate of $5 is non-negotiable, so there's the y-intercept. Then, the slope is 0.1, because it depends on the x-value. So, for this y = 0.1x + 5 It says he wants it less than 20 dollars 20>0.1x+5
