(10 pts)a surf instructor has an initial fee of $12 and charges $8 per hour for lessons. write a linear equation that represents the total cost of surf lessons after a certain number of hours.1.y-intercept  =  (0,  12),  point  =  (x,  y)2.m  =  83.  8  =    y  −  12x  −  0    →  8  =    y  −  12x4.solve for y: (dropdown)y=8x-12y=8x+12y=12x-8y=12 x+8

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

Tickets to a science exposition cost $5.75 each for studentd and $7.00 for adults. how many students and adults went if the ticket charge was $42.75

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
