5) The graph of the parent linear function f(x) = x is shown in black on the coordinate grid. Write the function that represents this function with the indicated parameter changes. Slope (m) increased, y-intercept (b) unchanged.
Slope (m) decreased, y-intercept (b) unchanged.
Slope (m) unchanged, y-intercept (b) increased.
Slope (m) unchanged, y-intercept (b) decreased.

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

Plz hurry evaluate the expression a+b where a=8 and b=19
