What is the y intercept from this problem. The slope is 90

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
