Question

Can someone help with 3

Answer 1

`(5)/(2)`

Explanation:

For this graph we use function f(x) = kx or y = kx

In this case we have to find k (the slope) so we choose the point through which the line passes. For example point: (2;5)

2 is x and 5 is y

Now we have to put all the numbers to function and solve k.

y = kx

5 = k2

k = 5/2
