Answer:
Value of c=8
Step-by-step explanation:
In this example we are given two points, (9, 7) and (10, c), on a straight line.
o let's take (9, 7) to be (x2, y2). Let's take the point (10, c) to be the point (x1, y1)
Fomula of slope is y2-y1/x2-x1
=7-c / 9-10
=7-c/-1
-1=7-c
-1-7=-c
-8=-c
c=8
Hence Value of c is 8
