Question

A linear function has a slope of 7, and when x is 3, the value for y is 22. use a graph or table to figure out the equation of the function. show your work.

Answer 1

Let y = mx + c be the equation of the linear function.
Since the function has a slope of 7,
we get m = 7.
So,
y = 7x + c
When x=3, y=22:
Substitute these values in the above function to find c:
22 = 7(3) + c
c = ?
