Question

Find the straight line f(x) which intersects the coordinates (8,0) and (1, -7).

Answer 1

Answer:

f(x)=1x-8

Step-by-step explanation:

slope: 0-(-7)/ 8-1 = 7/7= 1

eg. (1,-7)

-7= 1 -y int.

y int. = 8

therefore:

f(x) = 1x-8

Answer 2

Answer:

y = x - 8

Step-by-step explanation:

7/7X - 8

the y intercept was the only tricky part
