Answer:
Step-by-step explanation:
The best range would definitely be 0 to 670. However, the middle ordered pair given by Marcus is not (5,310) but (5,410). That's because y = 52*5 + 150 = 260 + 150 = 410.
When he graphs the equation; the best range for y is; 150 <= y <= 670.
The range of an equation as that which is in the task content refers to the set of possible y-values for the equation.
On this note, since, the smallest value of variable y which corresponds to the y-intercept is 150. It follows that, the lower limit of y-values for the equation is; 150 and since the highest y-value is 670, it follows that the higher limit is 670.
Ultimately, it follows that the range of the equation is; 150 <= y <= 670.
