Slopes, y-intercepts, (& points)

the membership to your local video store is $10 per year and the dvd rental rate is $3.95 per dvd. right in equation that models the total amount of money you will spend on dvd rentals this year.

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

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

Are the corresponding angles congruent? explain why or why not.
