Aline with a slope of 3 passes through the points (9,7) and (10,c) what is the value of c?

plz !

 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

hello! just here for points! though i wish i knew!
