Graph the solution of the inequality on the number line. −2x + 5(x − 2) > 7x – 6

Question

If you were to graph −2x + 5(x − 2) > 7x – 6 on a line plot, where would you plot it?

Answer 1

add 2x to get

5x-10> 9x -6

4x < -4

x < -1

plot the line x=-1

then shade in the area left of that line as the solution, but that's 2 dimensional

on a line plot, the solution is the interval (negative infinity, -1)
