Answer:

k = 7

Explanation:

Points on graphs are written in the form (x, y).

In the point (k, 3):

x = k

y = 3

Substitute the values for x and y into the equation.

2x + y = 17

2k + 3 = 17 Start isolating k

2k = 17 - 3 Subtract 3 from both sides

2k = 14

k = 14/2 Divide both sides by 2

k = 7

The value of k is 7.
