A cable TV company charges ​$24 for the basic service plus ​$8 for each movie channel. Let y be the total cost in dollars of subscribing to cable​ TV, using x movie channels. Find the​ slope-intercept form of the equation.

Answer 1

The slope-intercept form of an equation is in the form y = mx + b, where m is the slope and b is the y-intercept.

In this case, the basic service has a fixed cost of $24, so the y-intercept is 24.

The additional cost for each movie channel is $8, so the slope is 8x.

Therefore, the slope-intercept form of the equation is y = 8x + 24.
