Question

I am horrible with these problems!

A line with a slope of -1/6 passes through the points (j,3) and (8,2). What is j?

Answer 1

j=2

Explanation:

take the second numbers in each parentheses and subtract them. put this answer on top of a fraction

(j,3) (8,2)

2-3 = -1

take the first numbers and subtract. put this answer at the bottom of fraction

8 - J = 6

j = 2

answer should equal -1/6

the formula for a slope is y2-y1/x2-x1

look at the points like this, and fill in the places with the numbers and j they give you

(X1,y1) (X2,y2)
