Given the (3,4) and the slope of six find Y whenX equals 27

It's a linear function of the form y = m. x + b.

We know the value of the slope m = 6 (given), so the equation becomes:

y = 6. x + b. To calculate b, plug in (3,4), where x = 3 and y = 4

4 = 6 (3) + b

4 = 18 + b and b = - 14

Then the function is: y = 6. x - 14
