Please help if you answer this correctly I will give you brainliest. Is this a zero slope or an undefined slope? Picture below

Astudent survey asked: "how tall are you (in inches)? " here's the data: 67, 72, 73, 60, 65, 86, 72, 69, 74 give the five number summary. a. median: 73, mean: 70.89, iqr: 5, min: 60, max: 74 b. 60, 66, 72, 73.5, 86 c. 60, 67, 72, 73, 74 d. 0, 60, 70, 89, 74, 100

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0
