What is the slope of the line passing through the points (–3, 4) and (2, –1)?A.

3/5

B.

–1

C.
1

D.

-5/3

Answers

to find the slope, we find that by (y₁-y₂)/(x₁-x₂) so
(4-(-1))/(-3-2)=5/-5 and dividing a negative by a positive=a negative so the slope is -1
the answer is B

Slope of the line using the two points (-3,4), (2,-1) given.
x1 = -3, y1 = 4, x2 = 2, y2 =-1

m = (y2 - y1) / (x2 - x1).

m = (-1 - 4)/(2 - - 3).

m = -5/ (2 + 3) = - 5/5.

m = -1
Therefore slope, m = -1. So it is option B.

a teacher asked 3 pupils to choose any 2 digit number square it and then find the remainder after dividing the result by 7. Doris got 6 Marie got 4, Horace got 3. Two of the pupils made a mistake. Why?

Answers

First write out all the two digit square numbers

4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81

Next divide all of them by 7

16/7 = 2 2/7 or 2 and 2 remainders
25/7 = 3 4/7 or 3 and 4 remainders
36/7 = 5 1/7 or 5 and 1 remainder
49/7 = 7
64/7 = 9 1/7 or 9 and 1 remainder
81/7 = 11 4/7 or 11 and 4 remainders

This tells us that the only possible remainders for a two digit square number divided by 7 are 1, 2 and 4
If Doris got 6 and Horace got 3, they must have made a mistake.
