During a scuba dive, Lainey descended to a point 13 feet below the ocean surface. She continued her descent at a rate of 13 feet per minute. Enter an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 77 feet below the ocean surface. Use t to represent the variable for the minutes Lainey can continue to descend.

What is the solution to the system of equations? (–2, –8) (–1, –5) (0, –2) (2, 4)
