Question

The points (-1,6) and (1,r) lie on a line with a slope 4. Find the missing coordinator r?

Answer 1

Answer:

r=14

Step-by-step explanation:

r-6/1-(-1)=4

r-6=8

Therefore, r=14

Answer 2

Answer: The missing coordinator R is 14.

Step-by-step explanation:

6=4(-1) +B

6=-4+B

b=10

B is 10 and is the y-intercept of the line.

Now to find R  you use the equation y=4x + 10

so r=4(1)+10   r= 14
