Question

ANSWER 18 19 AND 20 AND 21 IF YOU CAN! OFFERING MANY POINTS! NEED HELP FAST, ALGREBRA 1

Answer 1

18. is integers because there are negatives, zero and positives. 19. is also integers because the values are the same as they were in 18. The friend actually plotted the points correctly, her mistake was that she didn’t connect the dots. The data is continuous. To draw the function correctly, plot the points in the places they already are but make sure to connect them!

Answer 2

review of numbers;

whole number: 0,1,2,3,4,5, etc

integers: whole numbers and their negatives so -5,-4,-3,-2,-1,0,1,2,3,4...

rational numbers: numbers that can be written in form a/b where a and b are integers, so like 1/2 and 3/5

real numbers: includes rational numbers and irrational numbers like pi

18

x values are -3,-2,-1, 0, 1 which are integers

19. for y=x+3, you cand use any real number, so the answer would be real numbers

20.I don't know what error our friend made since the plots are correct but the red loines are wrong

21. just connect the dots on the plot, plot (0,3), (1,4) and connect the dots witha line
