Sarah is on a road trip with her family if her mom is driving 105 kph, how can Sarah calculate how far they have gone based
on how many hours they have driven so far? Write an equation
for the proportional relationship.

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.

Is the ordered pair (-10, 7) a solution to the equation y = 17 – x? yes or no
