Express the following intervals in terms of inequality and graph the intervals

a.) [-6/7, 10]
b.) [ -5/2, 4]
c.) [-3, infinity]

a.) Inequality: -6/7 ≤ x ≤ 10

Graph:
Number line from -6/7 to 10 with a closed dot at -6/7 and an open dot at 10

b.) Inequality: -5/2 ≤ x ≤ 4
Graph:
Number line from -5/2 to 4 with closed dots at -5/2 and 4

c.) Inequality: x ≥ -3
Graph:
Number line starting from -3 to the right with an open dot at -3 and an arrow pointing towards positive infinity
