A sign next to a roller coaster at an amusement park says, “You must be at least 60 inches tall to ride.” Noah is happy to know
that he is tall enough to ride.
Noah’s friend is 2 inches shorter than Noah. Can you tell if Noah’s friend is tall enough to go on the ride? Explain or show your reasoning.

Answer:
y=-6
Step-by-step explanation:
Method 1:
Both the y coordinates of the points are the same and the x coordinates are distinct.
Therefore the straight line passing through the point is parallel to X-axis.
The common y coordinate is -6, therefore the line equation is y=-6.
Method 2:
We will solve it using general line equation
(y-y1)=()(x-x1)
where (x1,y1) and (x2,y2) are the 2 points.
- (y+6)=(
)(x+2)
- (y+6)=0
- y=-6
