Question

A function is graphed as a line. It is known that the points (-6, 10) and (-2, 12) lie on this line. Write the formula of the function in f(x) = mx + = b form.​

Answer 1

First find the slope by this rule:

Y2-y1/x2-x1 = 12-10/-2-(-6) =

= 1/2

Y= 1/2x+b (now you can replace any of the given points to find the b which is y-intercept)

12= 1/2(-2) + b

b= 13

Final answer :

Y= 1/2x + 13
