A linear function ff models a relationship in which the dependent variable decreases 4 units for every 2 units the independent variable increases. The value of the function at 00 is −2−2.
Move
+153 The slope is -4/2 = -2.
The y-intercept is (0, -2)
We can use this information to write an equation for the function and find the x-intercept, the x-intercept is the value of x when f(x) = 0:
f(x) = mx + b
f(x) = -2x -2
0 = -2x - 2
2 = -2x
-1 = x
The x-intercept is (-1,0)
Hope this helps!
