What is the equation of the line in slope-intercept form?

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

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x

Yvaries directly as x. y =90 when x=6. find y when x=13
