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

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
