2.) Priya is stacking building blocks to make a tower. She takes a break when the tower is 2 1/2 feet tall, which is 5/8 of the height of the tower she
wants to build. How tall is the tower when finished? Select the TWO
equations that represent this question.
5/8 x ? = 2 1/2
5/8 - 2 1/2 = ?
2 1/2 x? = 5/8
2 1/2 = 5/8 = ?

PLEASE ANSWER FAST :(

What is the y-intercept of the line given by the equation

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
