Solve the problem.The monthly cost of a certain texting plan is given by the function y = 0.07x + 9.95, where y is in dollars and x is the number of texts sent in a month. Find and interpret the slope and y-intercept of the linear equation.
A. m = 9.95; The number of texts sent in a month increases 9.95 for every dollar spent. b = 0.07; The number of texts that can be sent when x = 0 is 0.07.
B. m = 9.95; The cost of the texting plan increases $9.95 for every text sent. b = 0.07; The cost of the texting plan is $0.07 if no texts are sent for the month.
C. m = 0.07; The cost of the texting plan increases $0.07 for every text sent. b = 9.95; The cost of the texting plan is $9.95 if no texts are sent for the month.
D. m = 0.07; The number of texts sent in a month increases 0.07 for every dollar spent. b = 9.95; The number of texts that can be sent when x = 0 is 9.95.
