Answer:
Step-by-step explanation:
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis represent
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The line passes through (9,-1) and (6,p) and the slope is 1
y2 = p
y1 = - 1
x2 = 6
x1 = 9
Therefore,
(p - - 1)/(6 - 9) = - 1
(p + 1)/- 3 = - 1
(p + 1) = - 1 × - 3
p + 1 = 3
p = 3 - 1
p = 2
