Question

Find the slope of the line that passes through (4, 1) and (7, –2).
–1

–1/3

1/3

1

Answer 1

To calculate the slope you must find the difference in y divided by difference in x.

Use this rule: \[\frac{ y2-y1 }{ x2-x1 }\]

Answer 2

(4,1) and (7,-2)
(x1,y1) and (x2,y2)

Answer 3

ok?

Answer 4

I know the rule,I just don't understand how to solve it.

Answer 5

Answer 6

Ok

So I wrote the first point is (4,1) so it will be (x1,y1)

The second point is (7,-2) so it will be in terms of ( x2,y2)

Answer 7

The rule is: y2-y1/x2-x1

SO: -2-1/7-4

It will be -1
