Question

Q # 13, write a rule for the linear function in the graph

Answer 1

From the two points first we need to find the slope (m)

$m= \frac{3+1}{4-3}=4$

Using the slope and a point (4,3) we can write the equation in slope intercept form as:

y - 3 = 4(x-4)

y = 4x -16 + 3

y = 4x - 13

So the correct answer is option A
