Question

For the linear function f(x) = mx +b, f(-3) = 14, and f(7) = - 6. Find m and b.
m=​

Answer 1

You can model a data using a linear function when the dependent variable is a multiple of the independent formula plus another constant by the y-intercept. The constant multiple is represented by the slope. In real life problems, linear function is applied when you want to determine the cost given with a slope which is represented by cost per unit time. For example, the cost of wifi connection is $10/month plus $2 inclusive for phone charges. The linear function would be:

C = 10t + 2

where C is the cost and t is time in months
