Question

Item 9 Write a linear function f with f(4)=−3 and f(0)=−2

Answer 1

Answer:

y = -x/4 -2

Step-by-step explanation:

Linear function is in the form;

y = mx + b

The first point is (4,-3)

so we have;

-3 = 4x + b

The second point is (0,-2)

Thus;

-2 = 0(x) + b

b = -2

Put this in the equation above

-3 = 4x -2

-3 + 2 = 4x

4x = -1

x = -1/4

So the equation is;

y = -x/4 -2
