Question

Which of the following is the slope between the two points (4, 2) and (3, 1)?

1

-1

2

-2

Answer 1

Y(2)-Y(1)/X(2)-X(1)
that is your formula. Jut plug in the X's and Y's

Answer 2

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 3

insert the points into y = mx + b as follows:

1 = 3m + b
2 = 4m + b

Isolate b in each equation

b = 1 - 3m
b = 2 - 4m

set b = b

1 - 3m = 2 - 4m

Place like terms on the same side

4m - 3m = 2 - 1
1m = 1
m = 1

Answer 4

x would be 4 and 3/ and Y would be 2 and 1 right?

Answer 5

yup

Answer 6

If you use my method, you won't have to remember anything except y = mx + b

Answer 7

3-1=2
4-2=2

Answer 8

@Solmyr, you're confusing me bro. That's not how you do it.

Answer 9

ok
