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.
