Question

What is the equation of a line that contains the points (0,8) and (8,8)

Answer 1

Answer: y=8

Step-by-step explanation:

The equation for a line is y=mx+b

m represents slope and b is the y intercept

8 is our y intercept, and this is how high or down the line will go, in this case it is 8 because of (0,8) because x is equal to 0

lets find the slope using: y2-y1 / x2-x1

and we are given (0,8) and (8,8)

0: x1

8: y1

8: x2

8:y2

simply plug in

8-8 / 8-0

0/8

= 0

so 0 is our slope

so:

y=0x+8 or y=8

you can also check this by going onto desmos.com/calculator or by using a graphing calculator like a ti-89 and see that both will go through the line of (0,8) and (8,8)
